    PSA - popped up on the local board. Not mine. Appears to have the anti-compression sleeve on the cable.

    MMBA ? View topic - Slingshot MTB size small for sale $600

    <a href="https://www.flickr.com/photos/rmplum/14803139720" title="smallsling by Mr. P, on Flickr"><img src="https://farm6.staticflickr.com/5558/14803139720_e9589b63aa_b.jpg" width="960" height="717" alt="smallsling"></a>

    If you need a local contact I can probably help - though I am not sure exactly where it is in Michigan.

    Never understood why anyone would want to use that anti-compression bar. Variable wheelbase Sling action is the best!

    Hi All,

    Anyone know the diameter of the seatposts in the early 29er 'shots? Mine has an insert jammed in there good and tight to use a 27.2mm post but it looks all half assed and wrong to me.

    Cheers,
    Mat

    I believe it's 31.8 on any Michigan made steel 29er (BigShot).



    Later (overseas made) FarmBoy and Ripper bikes all use 27.2 seatposts.

    Thanks fatchanceti, that makes more sense. Just didn't look right with the skinny post coming out of that fat seat tube. Ye Gods, more surgery required and this frame has already been through the ringer! A previous owner has glued a new dogbone in on the skew, alignment is a whole 40mm out front to back, how do you do that by accident? Anyway it rides OK for now and looks pretty so I'll just keep adding jobs to the list until I have the nerve to tackle them all at once.
    Incidentally is anyone with me in thinking a Slingshot is about the dumbest starting point for a single speed? Dog bone guy had this frame converted for reasons best known to himself. still, he also had the canti mounts removed and disc tabs fitted so he wasn't completely deranged! ( seriously though, if you are out there Dog bone guy, drop me an email, I'd love to pick your brains about this frame) Add new dropouts and a mech hanger to that list...

    Here she is looking gorgeous in a little black number!

    Honestly, I think the Sling frame is an excellent platform for single speeding.

    Fun, fun, fun. The direct power transfer of a SS combined with the Slingshot frame is. Terrific match IMHO.

    Slingshot sent me an email last week about having a limited amount of replacement boards if you need one. "Sling power " makes for a great ss.

    Thanks for the comments guys, I must say I'm warming to it. Had a fantastic ride today which helps. I first bought the thing because it was a single speed frame in my XL size which is rare enough, and also for novelty value. After a while though it got stripped and hung on the shed wall. I guess I was disappointed with the rubbery feel. Rebuilt it last weekend for something to do and something has changed-maybe I have, but Im loving it!
    I do reckon that what you need in a single speed is light weight and a frame stiff enough to resist big effort out of saddle climbing in the wrong gear and you can't tell me the old Slingers have either of these attributes! Still, looks count for a lot in my book and its got to be one of the best looking bikes ever made.

    Ride on!

    Shipping charges 150$, no thanks. Before paying that much i'll carve a board by myself.

    Anyone have pics of Martin Stenger's race bikes? I'd like to see more of those, I only really have a couple scans of his earlier bikes.

    Vintage Slingshot

    Official Slingshot Bikes Thread-slingshot-001reduced.jpgOfficial Slingshot Bikes Thread-slingshot-002reduced.jpgOfficial Slingshot Bikes Thread-slingshot-003reduced.jpg

    Hey all. I bought this Slingshot at auction a few years back and I'm just now getting around to working on it. I'm guessing it is from the early 90s based on components and the neon green top tube, but not sure, in part because of the block-style letters. Any insight into this bike? I contacted Slingshot and they are doing a check into the serial number for me, but they also said that block letters were used prior to the stylized tube logo. A few others have thought it might have been race team issue and that SLINGSHOT in block letters was easier to see in a race, but I've seen other photos of race issue bikes with the stylized logo on the tube. I'm just trying to learn more about this bike. Thanks for any help or direction you can provide!

    I remember when you posted this bike a few pages back. Not much progress, but a very cool bike!

    Howley's estimate is right on. 1989 had the double top tube with the coil inside the top tube(s). 1990 still had a double top tube but the coil was moved down to the BB. Somewhere in late 90 (think they say 1990 1/2) they moved to the single boom tube with the coil still down by the bb. I'd say early versions of this bike (1990 1/2 and possibly in to 1991) had the block letters. As you said, the stylized 'SlingSHOT' logo may not have been designed or in production quite yet. I've seen single boom tube with coil at the bb with the stylized 'SlingSHOT' decal as well.
    You could order any color combo from Slingshot that you wanted, so paint might not be the best indicator of it being a team bike. The decals do give it that racy look and while it's possible it belonged to a sponsored rider, its tough to say unless Slingshot has records of that.
    Martin Stenger's 1991 bike was the same bright yellow with a red back end, block decals, vertical 'True Temper' logo on the Rock Shox Mag20 fork. Team bikes typically ran Syncros, Suntour, and Dia-Compe. This looks like an off the shelf M732/4/5 XT build. Stem changed somewhere along the way as that Zoom is a bit out of place.

    It'd be great if Slingshot has a record of serial numbers, but with all the ownership changes...hard to say whats been lost along the way. Keep us posed on what they say.

    Whats the restoration plan for it?

    Thanks for all the great information. Just what I was hoping for.

    How embarrassing. I forgot I posted here when I first bought it. You're right, I haven't done anything with it, but I re-read your comments from the first post and will definitely change out the stem and replace the tires on this bike. I do remember learning that restoring old shocks is not for the inexperienced. Seems I remember spending half my free time trying to find parts. So I guess the restoration plan is to get it back into safe rideable condition while using parts from the period if possible. I'm definitely open to suggestions.

    After many variations over the years, my longest owned VRC bike is finally getting a rebuild back to original 1992 Team race spec. I have a ways to go.

    Part of me is sort of happy that my current sling didn't come with a factory paint job. I feel like it gives me a little mental leeway to try some crazy things with it. The BB is pretty low on these, will probably still be well under 12" with the bigger wheels (if the rear fits - ).

    Went for a ride this morning with the man himself. Mark is a super nice guy as is his wife Nancy. My son thought it was cool riding matching bikes with him. Talked a lot about his new creation in Alter Cycles. Can't wait to take a look at one.

    Pretty stoked on this find. It's the test bike from the Feb 1992 Mountain & City Biking Magazine review. Sold to the friend of a guy who worked at MCB, it wasn't used too much and remained almost exactly as it was in the magazine photos. Corrected a few out of place parts and some fine tuning and it was back on the trail.

    Nice bike for sure. Never rode one but remember seeing one for the first time and thinking, "Does that...can it possibly, actually worrk?" I guess so.

    Just made the connection to the black and white slinger above. It's dazzle camouflage. It was used in WWI and WWII to a lesser extent. It wasn't to hide the object rather make it harder to target the ship in terms of direction, speed, and range. As rangefinders became common, it wasn't so useful as it was better at confusing the human eye than machinery.

    When I was talking to the previous owner about it, his buddy who worked for the mag said it was considered 'bad form' for them to return the bikes that were reviewed. So Mountain&City Biking (which became Mountain Biking) ended up with a store room full of decked out bikes. Sounds like they were occasionally sold off to friends and family. Hard to say would could still be tucked away in the garages of those who worked at these magazines back in the day.
    Guys like Jimmy Mac and Zap must have so much stuff.

    SlingShot Frame and Fork-The way it should be. This is the peak of the SlingShot reign, before attention moved to front/rear suspension.

    My day job is testing cars. I had a bunch of that camo tape left over from various prototypes we tested last year. Wondered how it would look on a bike. That stuff is super durable.

    The "medium sized" wheels totally fit on a mid 90's Slingshot by the way

    I worked in a bike shop in the Los Angeles area in 1989-90 and the manager ordered a Slingshot. The paint choice was any 3 Imron colors, so he chose some odd brown, grey, blue colors. Slingshot offered me a deal on a frame, so I got one. Despite a few issues, I've been hooked on Slingshots ever since. I think I've owned 6. Some that failed were traded in for new ones, which is always a sad occasion. Slingshot really stood behind their bikes though.

    Here's one from around 1992 or 1993 I think. It's the lowered boom tube, but pre-suspension. I found it used at Slippery Pig Bicycles in Phoenix a decade back. It's an XT/Nukeproof 7-speed mix:

    Official Slingshot Bikes Thread-20130121_220719_zpse37b163a.jpg

    My locale is rocky and I'm not 23 anymore, so the Softride stem let me ride this bike more than I otherwise would have. But I think these stems work much better in combination with the Softride beam than by just adding one to some other bike. I store this one at a friend's in Portland, and I miss it. (Especially since one of you said 650B wheels fit.)

    Here's a 650C time trial Slingshot I found on Craig's a couple of years ago. It was trimmed in a worn out Ultegra 7-speed group, so I put on some various Dura Ace parts from my hoarding bin to give it some style. I tried to set it up as a general roadie bike plus the aero bars.

    Official Slingshot Bikes Thread-20140614_192604_zps96ba48de.jpg

    This roadie Sling is really fast. Despite the weird proportions, it fits me well, and it's a rocket on a flat ride like a coastal bike path. Yes it's busy, a little wiggly, but we're getting to know each other. I'm keeping it.

    They fit fine in the frame, the biggest issue is the rear canti cable stop. Finding a balance between tire clearance and topping out on the stop took some real fine tuning. Here is a shot when I was originally tweaking things. It works ok, but obviously not ideal. The Shimano SLR+ brake levers salvage it.



    This frame in particular came (from the original owner) with a 410mm A-C Kona fork, so there is TONS of clearance up front for a Pacenti Neo-moto.

    That is tight. There's very little room for the cable to move.
    Each bicycle owned exponentially increases the probability that none is working correctly.

    Yeah, that was my first mockup. I have it set slightly lower now and it functions pretty well without "topping out" on the stop. I have a Cane Creek Direct Curve linear pull brake that will also work on the big wheels and eliminate the cable stop function, but for now this functions ok. I don't really take this thing out mudding, and the 650B wheels are pretty fun.

    Do we like new Slingshots?

    No, we don't like new Slingshots.

    Let me digress. I'm disappointed that Slingshot doesn't make any suspension frames locally. Maybe some of their current offerings are still worthy? I like the idea of continuing to support them if possible. Just throwing that out there. Old bikes rule. A funny reaction from a riding friend: "You bought a new Slingshot? Who's buying new Slingshots?" I sorta did.

    My old Slingshot doesn't fit a suspension fork, and I knew I'd ride a Sling more if I could put a fork on it. A couple years back my Craigslist trolling led me to a brand new Fold-Tech frame for $500. I have a travel road bike, so a travel mountain bike was desirable. I grabbed it and built this up:

    Official Slingshot Bikes Thread-20130922_103030_zps77263c18.jpg

    I know, not vintage. But still retro and classic? Maybe. (I'm trolling for bonus points for the old Sid, Ringle post, bar ends and Cane Creek brakes.) Altogether I spent about $1250 on it, cheap for a cool custom bike. I thought I'd offer a review.

    This is a different animal than the vintage Slingshots. It's an aluminum boom tube and steel rear triangle. But made in China means there can be compromises. First and foremost, it's weighty. This bike is a tank. It's fast, but heavy. Yes, I'm guilty of hanging a few too many Jenson and Nashbar closeout parts on it, but still, this frame is stout. I bet they get no warranty claims. Gone is any hint of side to side flex. This thing is super stiff and isn't wiggly at all. And it still has Sling-Powertm. It's a nice rider, and I'm glad to have a Slingshot with a fork at last. The frame is certainly overbuilt and probably fine for someone heavier than my lean 160 lbs. And since Americans are usually...uh...bigger, I could see a larger(!) audience for this bike.

    It does fold or come apart for travel. The tools required are unusual. Loop a strap through both wheels near the ground and buckle the ends. Step on the strap to slacken the cable, then pull the grenade pin that holds the cable to the bottom bracket. Remove the seatpost and then remove the main bolt behind the board with a 14mm socket and an 8mm Allen. I put Bruce Gordon Quick Switch connectors on the gear cables to make it easier. The brake cables unhook at the levers. The rear brake cable is designed for full housing that zip ties to the boom tube, so I'll carry a few extra zip ties when I travel. (I hate that.) I could have done disc brakes, but the non-disc wheels were cheap and should pack smaller too. It fits handily in a Ritchey Break-Away suitcase. Given the VRC style guidelines here, I won't mention that the 2x10 setup (my first) is excellent.

    I like the look of it. It's still fairly old-school Sling, and I'm pleased with the red trim. It's not so horrid looking as a Ripper, is it?

    I've had a few of the newer Slingshots (I've owned maybe 8 or 9 to this point - lost count). They ride perfectly fine (the concept really hasn't changed, and the user serviceable dogbone is a huge bonus) - but yeah it wouldn't kill them to maybe hire a industrial designer or someone to clean the frames up a bit. Your bike looks ok to me (there have been much much worse posted here) - the one part that sticks out is the huge (and abrupt) taper down from the boom tube to the dogbone mating area (and the rise bar + bar ends deal). The Ripper is sort of a mess, especially in 29er form. I appreciate function over form, but there's a limit.

    Ha! Great thread. I was searching for some info on my old bike....I've had it forever and ran across this goldmine. Liked it so much I registered. Can anyone tell me what year my Slingshot is? I've had it since the late 80s or early 90s. I do have the original steel fork too. Funny that mine does not have any decals like most I see. This picture is from several years back, but besides the tires no changes. Deore DX and XT I think. 7 or 8 speed will have to check. Been doing lots of road riding but this thread might make me dust it off and take it for a spin.

    I love when this thread pops back to the top. Welcome!

    Double top tube, coil down low would be late 1989 or early 1990.

    Please put the rigid fork back on it and take some good pics to share!

    Thanks for the quick reply. It does have the spring/coil down at the bottom with some protective thing over it. I really dig the bike. it was my off road staple in the 90s, then slicks on the campy MTB rims for some time. Now it mostly hangs on the wall of the garage. I'll have to dig out the fork and get some proper pix. Any idea why no stickers? I think it does have a head badge....not a sticker but proper old skool head badge. Old Klein bars on it too. Think they were called airplane or aeroplain or something like that. EDIT: Make that Mission Control. Remember them being super light back in the day....and rather spendy.

    Slingshot frame change timeline with pics lifted from the internets. My understanding is that changes happened along the way as needed, so there's some gray area on exactly when the changes took place.

    1985 - 1986 - double round top tube, flat plate, double cable, BMX headset, first gen decals.



    1987 to maybe 1988 - double round top tube, single round cable anchor, double cable, BMX size headset, first gen decals.



    1988 - 1989 - Double round top tube, single 'hidden' coil inside the top tube, second gen decals.



    1990 - Double round top tube, coil down low, second gen decals.


    1990 1/2 and into 1991 - introduced the 'boom tube', coil down low. The block letter 'SLINGSHOT' is early in the boom tube timeline. Later 90/91's have the 3rd gen decal.


    Late in 1991 the coil gets moved up to the headtube, still using integrated seat binder, 3rd gen decal.


    1992 - Boom tube, coil up by the headtube, external seat collar, 3rd gen decal.


    1993 - 1995ish - Boom tube, heavily slopping top tube, seatpost size increases to 31.6, 3rd gen decal.

    Neat thing with earlier Slingshots was that each one was different from then next in terms of build and paint. I can only assume the first owner either peeled off or requested no decals?
    A Mission Control would have been a smart cockpit set up back then. I'm guessing the elastomers in the Manitou 1 are dust/gum. They really do ride best with the rigid fork on there anyway.
    I thought the solid silver head badge came with the Boom Tube bikes, but I guess it's possible they're on earlier bikes.

    Rebuild yours in its period correct glory and go ride it. It's like reliving your youth.

    I have a set of the right decals for that bike in my storage unit. Might be awhile before I get to them but when I do I will let you know if you are interested in them.
    A bike by any other name is still a bike.

    No comments from the peanut gallery!

    Say what you will, but my Slingshot love has stayed true regardless of my 'collecting' evolution.
    For me they're still a blast to ride and I'm familiar with their (few) short comings. I have no illusions about their market value or desirability, though I think it should be higher on both accounts (not sure if thats bias or not).

    Cool thing about Slingys is you always get spares for them.

    Here's a whole heap of downtubes, or whatever they're called.

    Bonus:

    Totally compatible (and insanely fun) with this crazy new 650B fad that all the "kids" are into these days



    I've been riding it with the sorta big wheels for some time now, and it's fantastic. Plus to make it even weirder I grabbed a rim brake compatible ENO eccentric rear wheel off eBay. Sling + 27.5 + singlespeed = insane fun.

    I had to scrap the tri-aligns. Moving the pads up as high as they needed to be on the posts yielded super el-sucko braking.

    The Cane Creek direct curve 5 brakes work great now (using them with Paul canti levers) - I just need one more of them to be all set (running one of the chinese carbon front forks with a Hy/Rd disc as a placeholder). So no, mine is nowhere near period correct, but it kicks all sort of butt, is fast, and I am riding the crap out of it.

    I'm confused about one of my Road Slingshots because on mombat they write:
    MOMBAT: Slingshot Bicycles* History
    1991 ... Custom road frame built for Martin (after many requests). ... Triathlon frame is now available and uses 26" wheels.
    This one has 28" wheels and looks older for me (1989?). It was from a shop called Brima in the Netherlands. Here's a mockup.


    Here a picture of his MTB brother which stands in the MTB Museum Arnheim.


    If it's not visible because of my bad picture, they have the same paintjob with different decals.

    hey, question for the slingshot experienced.

    How tight do you keep the cable? I built up a 1995 Slingshot and it twists quite a bit while riding. Is this normal? will tightening the cable tighten up the frame? I get the up and down action but the side too side movement seems a little crazy. Anyway thanks for your input.

    Slingshots? Flexing? Unpossible!

    Well maybe...

    The cable: Slingshots have just a little vertical movement, so the unweighted geometry is not much different from the weighted geometry when you're on the saddle - they don't have much sag I mean to say. The flex comes more within the power stroke. Thus I think the cable tightness should reflect the geometry desired, around 71/73.

    The cable tension doesn't affect the side-to-side flex. There just is some of that in the design. There's a way to ride a Slingshot - you can minimize the twist, and you can work with it too. The Slingshot is for the nuance rider, the gazelle, not the Clydesdale. Yours is a '95 - does it have a suspension fork? If so, that adds to the flex, esp. if it's a vintage fork. Not much to be done there.

    One old magazine review mentioned how the Slingshot's wheels can track independently more than a rigid frame would allow. Over the rough stuff, the bike can indeed be all over the place. But somehow it works. You Sling your way over obstacles that might stop another bike.

    The new models like the Slingshot Fold-Tech that I have do away with much of the lateral flex and twist. They are quite stiff, but they are seriously weighty too. The vintage model you have is highly regarded...despite its quirks. It's light and it moves around - work with it and you can be very fast.

    Thanks for the response, I'll bring it out in the woods and see how it feels. Forks are Tange switchblades. It's a bit unnerving to ride. It reminds me of a skateboard with pedals.

    Something sounds fishy. Slingshots ride differently, but I've owned a lot of them and none have been anywhere near what I'd call unnerving to ride.

    Yes, definitely check for cracks.

    The "independent" front and rear wheel paths are pretty noticeable when you first start riding. If you go into a turn hard, it will feel weird at first. However, it starts to feel "normal" after a while.

    I rode Slingshot for a while and liked it as long as I didn't ride other bikes. Switching between the Slingshot and other bikes didn't work for me as the oddities of the Slingshot took a while to adjust to after coming back to it.
    Each bicycle owned exponentially increases the probability that none is working correctly.

    The fiberboard isn't cracked, but it did come out when I removed the bolts. the seller shipped it with one side removed. I removed it cleaned it up and put it back in and tightened up the bolts. Does it need to be glued in. What happens is when I'm sitting on the saddle and apply torque through the pedals the frame moves visibly to one side or the other. Something is weird, it's not subtle. I'm not very heavy, 180-185 or so.from what I read It should be glued in and difficult to remove. Thoughts are appreciated.

    Any idea what kind of glue? 2 part epoxy maybe? maybe I'll have it painted while it's apart.

    Aw sh!t, that's not good. Those boards are epoxied into place. I'm not entirely sure the process Slingshot used, but I'd say it was pressed into place with some pressure along with that epoxy. It definitely shouldn't have play or slip right out.

    A good two part epoxy should do the trick, but if enough of the fiberglass material has been shaved away, there could still be a problem with reliability/safety (and general frame alignment). I'd tap Slingshot about it and see what they say. They might even be able to get a new board in there for ya.

    When I was a club builder, we used Epoweld. It bonded graphite shafts and alloy heads and withstood the hard repetitive impacts of ball striking (enter crude joke here).

    Golf club builder sites will have that or a similar 2-part epoxy that will be way stronger than like JB Weld.

    Thanks Eric, I'll look into that glue. The fiberboard is very snug in the slots and the tolerances on the bolt holes are really close. I'll use this opportunity to paint it and then get it glued up. I have access to a frame jig and an alignment table I'll get locked ito place before the glue sets. BTW, Trimble is excellent!

    My seatpost clamp let go last week. Looking for the correct size to replace it. 1996 Slingshot, 31.8 post, ovalized seat tube at the bottom bracket. Anybody know? Thanks
    for the help.

    My bike is also a 96 - can you measure what's on there currently? If not, I can measure mine tonight and see if there are any ID marks on my clamp.

    Salsa makes the Liplock in 35.0 and 36.4mm versions.

    The 35mm (1.6mm wall thickness) would be my guess without looking - as my 'Shot uses a 35mm (34.9) front derailleur.

    Just joined the group - I'm from New Zealand.

    I imported my Yellow 1993 MTB3 17" frame, fork & double bottle holder direct from Slingshot - never seen another one here in all my 30 years of cycling.

    Built the bike myself over a period of weeks - it still make me smile when younger guys wonder how on earth I can get so much uphill speed.

    It uses Suntour Microdrive with grease guard groupset & has suspension in the handlebar stem (just like my touring bike - to remove the constant shaking from being on the road for hours when touring).

    I have also used it for the big bike ride here in NZ that is around our biggest lake - 160kms long, with my quickest time being 5 hours 15 minutes, by changing the 42 tooth for a 44 tooth.

    That think looks like it's fresh out of the catalog!

    Very cool you've had it all these years and still ride it.

    It has been changed slightly over the years - handle bar stem was fixed type, it originally did not have suspension + I have bought various Microdrive spares over the years to make it look new again.

    Decals?

    Hi all,
    My Bigshot is in for surgery and a re-spray; I'm sure you've heard this before but does anyone have a hi-res file of the Mk 3 boom tube decal I can send to the printer?
    Many thanks,
    Mat

    When you say MK3, do you mean MT3 (like my yellow one a couple of posts above?) - if so then I should be able to scan, as I have all the color options that were available from the factory - still not used & in mint condition....

    Yes that's the one, just like yours! Would be fantastic to get a really good scan if you can find the time. Many thanks.

    And 8,000 people do the round Taupo race each year.
    A mountain bike race on an old classic mountain bike seems more fun.

    MT3 Decals - here you go as promised, there were actually 3 variations (I still have 2 sets of each never used) - I have only done the set that gives the best contrast - the other 2 had lots of white and hence outlines were not clearly defined.

    Print the attachment on A4 - this will give you full size.


    To see where the main ones are fitted then see posting number 659

    Also check out posting number 522 .....

    New Tires fitted.

    Got some pretty cool 26 x 1.5" tires - can't wait to see how they perform on the road later tomorrow.

    Notice the suspension on handlebar stem and double waterbottle holders .... same setup as my touring bike.

    New (old) period correct cranks for my late 90s Sling....(note the knobby tires - this thing gets ridden seriously and is my main MTB)

    +1 on the brakes. I have several pair of those Cane Creeks, and one set graces a Slingshot.

    Noodles goes to the races

    Well she's back from a long stint hanging in the shed and a short stay in the frame hospital. No longer a single speed she now has gears on the back at least and is a much more enjoyable beast to ride. First and probably last race was against a steam train here in central Victoria, which I thought appropriate somehow-aesthetically beautiful but obsolete technology and all that. Train won...
    Whats next for Noodles? Well, having decided I like her again in this mocked up form, I'll break her down for the respray and decals (thanks to Surteess), go 11 speed then a bit of bike packing and long gravel grinds that normal folks buy a CX bike for. Looking forward to it!

    Pretty hard to come by actually. You'd have an easier time finding and using a 1" Yeti (AccuTrax) fork.

    Timing, patience, and daily searches. If you get desperate enough, buy an entire other bike and pirate the fork from it.

    Other high end vintage options:

    IRD, Bontrager, Syncros Powerlite.

    Slightly less expensive, easier to find options:

    Ritchey Logic, Koski Druatrac (great fork BTW), Tange Switchblade

    If you want something that has a similar look to the Slingshot fork, a non suspension corrected Kona fork has the right look. Should be relatively cheap and easier to find than the others as well.
    Need: McMahon brake for roller cam mounts, Mountain Goat fork.

    what about Vicious Cycles? Vicious Cycles - Forks Their 413 ATC 1" would work, right? I realize not vintage, but really nice and would let you go (or force you to go) threadless.

    I havent been on the forum for a long time, so maybe you have figured this out...

    Its been a decade, but I emailed them and they dug up a threadless 1" canti fork for me from some pile they had sitting around. If you check with them (I'm assuming its a 1") they might have something...who knows! Also, if your looking to stay with a threaded fork, hit me up. I have my original one, though its painted white (I got my frame/fork unpainted in the early 90's then shipped it off for a custom job).... and I'd be willing to part with it for a good home.

    Cool pics, looks like New England's getting a brutal winter! My last winter there was 2015 and it was a doozy, but 2012 was the double whammy of Sandy and then 3.5' of snow, at least where I was in Old Lyme, CT. Enjoy the green grass while it lasts.

    Mr. Claus,

    Do you have stinging nettles in CT?
    Wasn't thinking about them this early in the season, but managed to kneel in a patch while setting up my camera...good times.

    Just got it tuned up and out of storage

    Started riding again after about a 10 year hiatus. Still rides awesome.

    Cleaned it up, thought about painting it but it really isn't bad except for chips here and there. Mostly original. Still have some of an aluminum seat post fused down inside someplace (never was able to get it out)but for the most part it still rides great. Got more narrow 'street' tires, etc.

    Now if only I could find some original "Slingshot" Decals. Mine is circa 93-94, all Shimano XT components, bought it in college, hah.

    Would really like to strip it down and re-powdercoat / paint it but not sure if it's worth the effort if it still looks decent

    Awesome! Great bike, I've got one in the same color. Whatever you do, don't repaint it if you don't have to. They're only original once. Besides, if you powder coat it, the heat will possibly compromise the epoxy bond of the flex board.

    I say ditch the cheapo Trek stem for something nicer with a bit more rise, put knobbies on it, and go on a mountain bike ride!

    I agree on the knobbies for sure BUT not a lot of mountains in FL I might go w/ some sort of hybrid/beach tire though.

    It's been FOREVER since I was mountain biking, but what would you recommend for a stem on this thing? Probably easy for me to swap it out for sure. I would love a bit more of a rise...My wife's cruiser bike makes me jealous.

    I kinda agree on the painting. I thought about sanding lightly the scratches and just spray on a little clear coat to keep them from rusting. Plus labor alone pulling everything apart I could be halfway to a decent new bike. IMHO nothing rides like the Slingshot though.

    Aah, ya. Location doesn't lend itself well to certain types of mountain biking. There have to be trails out there right? Just flat ones?

    If you paint, it'll have to be wet paint to preserve the flex board and the epoxy bond. That'll get expensive, not counting break down and rebuild if you're not doing that yourself. Up higher in this thread is a PDF scan of the SlingsHOT and True Temper decals. If you were motivated enough, you could have replicas made. Again...costly for a single set done properly.

    Stems most correct for a Slingshot that would give you a more comfortable rise and reach would ideally be a Salsa. You might find a Syncros or Answer ATAC that could work as well. Those would be period correct stems of great quality that fall in line with the rest of your bike.
    If budget and rise/reach are paramount....sky's the limit so long as it's a 1" quill stem.

    Thanks again. Yep we have a ton of biking trails although most are paved but still a lot of fun down by the water, etc. I was up near the panhandle last month and there are a bunch of trails on Eglin Airforce base that are open to the public. I go up there often and got the mountain bike itch a bit more.

    I'll peruse EBAY for an old ATAC or something similar. Upon first glance I could get something period correct around $40-50 bucks. I remember something about the stem not being big like new mountain bikes... I believe it's a 1". I've forgotten so much over the years

    Glad to see there are still some slingshots in use here!

    Had some decals printed up

    Well, had some vinyl decals made up from a decal shop using the pdf in this thread. They did the true temper ones too, but printed black instead of white and a bit too big...so we'll just go with 'original looking' for now.

    Can't believe i pulled these off in college and slapped weird moosejaw and other outdoorsy early 90's stickers in their place...but we're back to looking like a slingshot now

    Yah they turned out nicer than i thought...and w/ new vinyl stickers they should last a while although I did have a couple extra made just in case. Now to apply some wax to the frame and shine it up a bit. To other's suggestions on here too I don't feel a need to have this repainted at this point. I think a good coat of wax over the chips should keep rust at bay. So glad to be riding again.

    if you do go for a repaint, then paint frame and stickers and then do a couple of coats of clear over everything - mine was done that way 10 years ago and still looks great in the BMW565 yellow.

    Back again after almost 3 years away from this thread. After re-reading the thread as well as the archived MOMBAT site info about Slingshot, it's not clear to me what is meant by suspension fork-specific geometry. According to the MOMBAT timeline, suspension fork geometry was used on race team frames in 1991. I now have 2 1991 Slingshots, the one last seen in post #619 and one I just bought a week ago. Both came to me with RockShox. How do I tell whether either is a race team frame? If race team, I guess I should leave the RockShox on. If not, I'll find a suitable straight blade rigid fork for it. In 92, production Slingshots could have suspension fork-specific geometry on request. Does anyone know what that geometry is and how it differs from a standard production frame meant to have a rigid fork? Thanks for any help you can provide. Pics of the new one coming soon.

    Sorry, I just re-read Rumpfy's response to me in 2014 about really needing to trace ownership back to the first owner to determine if it was race issue. That aside, it still helps to know what the geometry differences are between suspension fork-specific geometry and rigid fork geometry.

    Custom 1991 Slingshot -- Flames, Zipper, and an Eyeball

    While visiting bike shops in the Grand Rapids, MI area looking for a Slingshot fork, I bought this refurbished or lightly used 1991 Slingshot that received a custom paint job at some time in its life. The guy I bought it from didn't know much about it and he just used it to tool around town. Funny thing is, I know I've seen this bike on the web in the past, possibly when looking for someone to paint a ti bike for me a few years ago. The artist's name is possibly on the head tube above the badge. It appears to be "Mitcher T." Anyone know anything about the bike or the artist?

    The build is mainly XTR, XT, and LX. Hubs are Nuke Proof and I'm told the carbon handlebar is NP too. See photos below. More in my album too.

    Comments appreciated. Still looking for a fork, though I'm still waiting/searching for an answer to the question about "suspension-ready frame geometry" I posed a week ago.

    How do I know if my Slingshot uses a board or a "dogbone"? just bought a cross frame on Ebay and I'm having it painted. Considering buying a replacement board/dogbone in case something should go wrong. thanks

    Dogbone might just be a slang term for the 3M flex board that was used at least through the mid 90s. There is a lot of good information in this thread about others wanting to do the same thing as you. Also, check this other VRC thread:

    http://forums.mtbr.com/vintage-retro...ot-707667.html

    You'll sense a lot of frustration concerning this topic. There might be some hope though. PJ Mc Donald at Slingshot sent me an email less than a week ago stating they still have the parts in their shop, but the expertise to do this is not available until later in the fall. And there is no guarantee even then. I have a 91 Slingshot mtb waiting for the same treatment. Good luck, let us know if you make any progress.

    If it's a cross frame (or a road frame) then it almost certainly does not have the new self-aligning, user serviceable "dog bone". Only the FarmBoy, Ripper and newer stuff like that will be dogbones.

    Cool bike! Should be a 90.5 or 91 with the coil at the BB. Keep an eye out for cracks at the headtube anchor point. Prone to failing as this was their first 'Boom Tube' execution.

    Bars are definitely Nuke Proof.

    I don't have an answer for you regarding suspension corrected geometry. I suppose a non-suspension corrected frame would possibly look a bit more raked out if it was running suspension...of which the one you posted does not. But I'm just using Colkervision here.

    Finding a Slingshot fork will likely be tough. The Kona Project II forks are pretty similar visually - it's what my mid 90's Slingshot came to me with.

    Thanks for the comments and advice, Rumpfy. Ha! Colkervision. I had to search for about 15 minutes to figure out what that was. An MTBR member who has a better than average ability to judge distances/angles from photographs? Couldn't find the initial post coining "Colkervision", but found many posts by Colker.

    Yeah, I've noted that neither of my 90/91 Slinshots have a gusset at the head tube/cable attachment junction. I guess that came later in 91?

    Still working on the rigid fork vs suspension fork question. A few people I know seem to "know a guy who will know". So, for the time being, I'm a rat terrier and this fork question is the butt I have my teeth locked onto.

    Yup, was still 1" in 1995 or 1996 when mine was likely made (paint was so thick it was impossible to read the S/N). I do have a 1" threadless carbon fork (straight legs with chromo fork and steerer) sitting in my attic. It's pretty long (long enough to easily run 27.5x 2.2 tires) but would work in a pinch.

    I'm essentially a newb here, but I'll try to help. Clean up the upper inner surface of your seat tube. Next, ensure the small split in the tube is the same width at top and bottom (i.e. seat tube not compressed at top from use of a too small diameter seat post previously). Then measure the inside diameter of the seat tube at several different points. Both of my early 91 Slingshots (both mtb) have 31.8mm (O.D.) seat tubes. A 27.2 mm seat post is the best fit, but one came with a 26.6mm seat post and the seat tube was narrower at the top because of it (and the split was essentially closed when the binder bolt was tight enough to hold(?) the seat post in place -- not good). The Tri frame I just acquired has a 31.8 mm diameter seat tube. I'll bet your bike is one or the other (27.2 or 31.8), but measuring and getting to know your bike is always a good thing. Search this thread for other emails discussing seat tube/seat post diameters -- I know it's been mentioned a few times with other members' bikes. Good luck with your build. This thread has been a great source of inspiration and information for me. You're in the right place.

    This topic has been covered in this thread, if not resolved definitively. If I recall correctly, the prevailing advice from this thread has been to do nothing unless the board is loose/broken and/or the boom tube is misaligned with the rear triangle. Some have made it sound like this is an onerous task and that a special jig is required to do it right, yet I seem to recall another post in which the guy said he used to do these all the time for Slingshot and that it was no big deal. When I inquired about a month ago about this, Slingshot Bicycle Co told me they have the materials to replace the flex board, but the expertise (one guy apparently) is unavailable at least until fall. The previous posts in this thread will help you, or at least give you a well-informed level of confusion.

    By the way, what size seat post did you end up using? It looks like there is a separate sleeve in your seat tube. If you haven't removed it yet to inspect the inside of your seat tube for rust/corrosion, I would.

    I haven't checked that seatpost sizing yet but I will. The shop has it now...I'll find out soon enough

    Our beloved Slingshots. They have become our daily riders! Searched far and wide a few years ago until finding just the right ones for us. The black bike joined the stable first. I think it's a '93 TR3 (doesn't have the small, extra gusset on the seat tube behind the board). It arrived with what I believe are its original GripShifts, which was great, because I've long used only GripShifts on my MTBs. The rims were the original Mavics, but they were worn out. Replaced them with some fresh, modern rims. The yellow bike joined the stable next. I think it is a '95. It arrived as a green bike with a full DuraAce group and Ritchey carbon rims. The paint was original, but was peeling from the frame in many places. Surely a faulty spray. Even looked like it was applied without a primer coat. Nevertheless, I had no choice but to strip the frame and repaint. I had to reproduce the graphics, and since I was doing that I chose to reproduce the block style, which I prefer over the latter style. Now I'm on the hunt for a Slingshot MTB!

    Slingshot

    Hello. My first post here. I bought it last year from a guy that was from Michigan. He said he had it a long time but said he was the second owner. He had a hard time parting with it but after a few months he ended up sell me this f/f and a bmx cruiser. He believed it was maufactured in 1988-1989. It has original paint and decals. Im into bmx cruisers and I was thinking of turning this into a single speed.

    Yes, 88 or 89 is about right. Take a look at my stolen bike flyer. Post #742

    I took a look. I will keep my eye out for it. Was it the same color blue as mine? And what part of the frame was white and what part was blue?

    The whole bike was blue and white splatter paint. The rear U brake mount is something that you do not see on many Sling Shots.

    Thanks,
    Chris

    Spotted this at a thrift store today. Any info on the round-about year or model? Also any info on the wheel set? Can't really find much online. The valves were unlike any I've seen, so couldn't put up the tires and take it for a test ride.


    Edit: Tried 5 times to upload image and each time after I click "upload" nothing happens. Uploaded the image to an image hosting website and posted below.

    I've got a slingshot Ripper frame and I'm trying to figure out what the fork steer tube size is. Does anyone know what size fork the Slingshot ripper takes (straight, taper 1 1/8)?

    In reply to SpeedoJosh: I just saw your post today, so my guess is you've figured this out by now. Anyway, I can't see the detail of the valves well enough to be sure, but I raced these same wheels in triathlons during the 90s. Betting they are hollow tube valve extenders poking through the carbon rims that seem odd to you. If so, then the tubes (or tubular tires) have presta valves that are inside the rim. The valve extenders thread onto the presta valve thread. Bicycle Sports was owned and run by John Cobb then. He was Lance Armstrong's aerodynamics consultant during the early years of LA's TdF wins. Cool find!

    I made a deal to purchase the Slingshot pictured above, planning to adjust it closer to historical spec, at least as far as handlebar and saddle. Who knows the name of that color? It's not purple or lilac exactly.

    Good for you. I had reached out as well. Please save it! I have owned two in that color previously. I always called them Lilac!

    Thank gawd. Awful saddle/bar/stem set up.
    Lavender/lilac is probably accurate enough.

    It's a 1992.

    There's a Slingshot mountain bike on eBay right now that looks almost new. I contacted the seller because parts of the story didn't add up, and it had a decal I haven't seen. Components and frame look to be from 1994-1996. It does not have the Greendale Bicycle Co. decal near the top of the seat tube. Instead, it has a vertical oval with "MT2" in that spot. The owner said he bought this bike from the original owner who lived next door, and to the best of his knowledge the frame has not been re-painted. Anybody seen this before? I recall MT3 being a model number, but I don't remember seeing that designation on a frame. Also, I know MT3 was available at least as early as 1993, so MT2 as a model number for this frame doesn't make sense to me. Otherwise, it's a nice bike (16" frame size) with entry level drivetrain. It's a folding mtb that even has folding pedals. The owner is an older guy that seems pretty nice and honest.

    Forgot to add this final thought: If this MT2 seat post decal was original and was a replacement for the usual Greendale Bicycle Co. decal, was this the time that Greendale was selling assets?

    That's a solid frame, US made - late 90s, early 00s vintage? - before the Farmboys and Rippers (made in China) became their bread and butter. I owned a similar vintage folding road bike and it was great. Seat tube is sleeved at the top, pretty easy to pull apart with cable separators. I bought mine in 2003 or 2004 but it had sat around for a bit and apparently was loaned out to Dan "Hug the Bunny" Koepel for a review (which I never saw).

    Deserves better parts than are on it, but like a Ritchey Breakaway, it will not ride any different due to the foldability - just a bit heavier. Mine came with a Pika Packwerks soft-sided bag.

    Here is a photo of the MT2 decal on the a mid-1990s Slingshot mountain bike mentioned in Posts 781 and 782 above. Can anyone explain the seeming replacement of the Greendale decal with this decal around 1995 or later?

    OK, I got the answer from one of the fabled MUDBATS.

    He said the bike "looks legit". The MT2 designation means it was a mountain bike with the 2 level of componentry. It seems the change of ownership of Slingshot occurred prior to this bike being produced and Greendale Bicycle Co was not the owner at this time. The MOMBAT website page indicates 1994 was the year Greendale Bicycle Co. sold the Slingshot product and patents, so the chronology seems to line up in my mind.

    re: check out my new slingshot for sale

    I bought the lilac Slingshot above. It's been living in the house as art while I decide how to set it up. It's very clean, with a dent and old bearings. The color is captivating to me. What a different era of bikes the early '90's were: tan sidewall tires, silver components, colorful frames and graphics, expensive lightweight shiat. That's when I came to appreciate nice bicycles. This one is mostly Suntour XC Pro Micro-Drive Grease-Guard 3x7, with XT brakes, assorted Bontrager wheels, accessorized with Ringle.

    Much improved over the stubby saddle and ape-hangers previously. It's a beauty, for sure. However, those cable housing runs look too long for your current set-up now.

    This.
    Though the above isn't my setup. The new setup is a next week project. More ELS is needed.

    They said there would be no math, but I worked with a mechanical engineer for a while and showed him a Slingshot MTB. He was intrigued and thought that the angle of the cable and spring helped pull the bike forward rather than simply upward. Makes sense to me. I'm a faster climber on a Slingshot and was trying to get a handle on what sort of increase in efficiency, if any, there might be.

    Rigid Bike
    Length of crank arm: 175mm, about 7"
    Diameter of pedaling circle: 350mm, about 14"

    Slingshot
    Length of crank arm: 175mm, about 7"
    Diameter of pedaling circle incl. frame movement: @365mm, about 14.5"

    Thus for a given pedal stroke, I get 1/2" more distance from top to bottom to do the same amount of work.

    1/2" divided by 14" equals 0.0357, about 3% extra.

    It reminds me of Biopace chainrings, but better because it's tuned exactly to me. And it lets me shift one gear higher on the climb and sprint away. Then when I sit and spin smoothly, the Biopace feel is minimized so I don't feel like I'm stepping off a curb with each stroke.

    Likely some of that 3% is cancelled by lateral flex in the frame (or weight), but it's not the seat tube flexing at the bottom bracket (like a Vitus). It's more like the whole rear triangle sways a little bit. I don't pedal perfectly straight up and down when out of the saddle, and the bike moves with me. Also the Slingshot's wheels track more independently, which I notice in rocky sections where the rear wheel, instead of always bumping over the top of a rock, might move a little to the side and go around it. I don't notice any more twist in the boom tube than in a titanium hardtail.

    I'd be interested in others' opinions or math about this.

    From earlier in this thread, Martin Stenger leading Tomac up a climb, right before Johnny sprints past him for the win, but hey, who beats Johnny T?

    Way to go! Where was the race and what comments did you receive about your Slingshot?

    The race was at Rocky Point, Long Island....technical single track with one long section of fire road. The laps were 17 miles and we did three of them. The race started in the rain so most riders stayed near the cars until the start and after the race most of us were so cooked all we wanted to do was drink beer. There were a few questions....I think people were surprised to hear the bike was from 1992 and that I bought the frame on Ebay for $200 last year.

    Look familiar?

    It's a 1959's Fletcher-Kain bicycle.

    Can't find the picture but I saw this design in a 1920's bike in an Italian museum. So it's been around for a long time.

    Cool-blue Rhythm My Slingshots....2008 Foldtech, 2007 Farmboy 29er , 1994 Slingshot with S.S. dropouts

    Hi Slingshot aficionados,

    I have really enjoyed this forum with the many pictures of amazing Slings and the wealth of info regarding these unique bikes.

    Although I prefer the early to mid 90s models, as of late, I am hard pressed to ride them regularly as they are becoming more rare and difficult to find. I opted for newer, heavier, less-lively aluminum/steel model offerings for regular trail riding. I ride both my Foldtech & Farmboy to train for races. I find that they are best suited for single gearing....Boy, they are excellent for suffering, and countering handling. It sure makes hopping on my sub-20 pound modern race bike a cake walk. I am a much better rider riding these things and I really appreciate the unique characteristics of Slingshots!


    My 1994 will be a bit of a prissy garage queen slated only for the odd glory ride once its built up with some period correct parts. Thankfully, I have the original rigid fork.


    If anyone has any info regarding my yellow one, I would greatly appreciate it. I would like confirmation of its year. 1994 is what I was told as a guesstimate.

    Hi there! I used to post here as Puguglybonehead but I ditched my old hotmail accounts (spam insanity) and was unable to recover my login, so I am back as Paddyosonic. Still have the red Slingshot I got from 993rs. It's been in storage for a while, but it's definitely coming out again this spring. Looking now for one of the mid-90s frames in the small size, if I can find one. Preferably the folding version. Nice to see this thread still alive. Still wish Slingshot would start making the old designs again. Wishing......

    Today I was wondering if anyone has thought of trying to make a Slingshot type of bicycle using carbon as the mainframe and rear triangle, and Kevlar for the cable.

    It's a potentially lightweight approach.

    The old cromoly-steel frames from the early to mid 90s were already lightweights. A 24-lb bike could easily be assembled on one of those framesets with full gearing and mid-high-end groupo. The 91/92 Slingshot I have is now a sub-20-lb singlespeed MTB. A titanium version would be marginally lighter. One with a carbon-fibre boom tube and ti rear triangle would probably be stiffer than an all titanium. (though an all-titanium Slingshot would still be my dream bike, folding version of course) The cable/spring/flex-board combination is an essential part of the sling-action formula. It doesn't add any weight, in fact the lack of a downtube in the frame probably saves some weight.
    The nouveau-slingshots are heavy becuase they overbuilt them to a ridiculous degree (6-lb frames?!?!!) all in the name of adding stiffness to a design that inherently will never be as laterally stiff as a conventional double-diamond frame.
    I say they should return to the mid-90s designs. They were very lightweight and as close to perfect as these bikes can get.
