    Show pics of your 1x9 setup

    It's the wave of the future. Simple, reliable, lighter. It has made me a better rider since I don't worry about getting my chain to drop into the granny gear on climbs. I just pick a line and hammer. It makes me stronger and more efficient without the knee-busting efforts of a singlespeed. Without the extra rings I can run a shorter chain and get a lot less chainslap. And there is nothing I hate more than trying to get a front derailleur to stop rubbing.

    I built this up over a few months by scrounging for good deals on lightly used parts on Ebay and buying OEM take-offs from JensonUSA. I got my hydroformed aluminum Planet X frame, King headset and Thompson seatpost from Ebay for $220 total. So far I've bought every part except the fork and wheels for ~$700. Retail would have been over $1500. I should end up saving about a grand by building it myself. I built it like this because I'm north of 200# and ride the very rocky and rooted trails at Turkey Mountain in Tulsa, so durability was a priority.

    Truvativ Hussefelt crank, 32T with aluminum bashguard, 22T removed. JensonUSA takeoff- $69
    Truvativ DHLT BB, 113x68. JensonUSA takeoff - $19
    SRAM PC-991 chain, solid pin. JensonUSA pricematch - $26
    SRAM X-7 rear shifter, JensonUSA takeoff - $30 for pair. Would have liked the X.0, just needed something to work with the X.0 derailleur for now. Still works great.
    SRAM PG990 11-34T cassette, the new red one. New in box from Ebay - $75
    SRAM X.0 Long Cage derailleur. Barely used on Ebay - $100
    Nokon cable housing ~$45 for front & rear, BlueSky Cycling
    Jagwire teflon coated cables, BlueSky
    NGear Jumpstop - $9 at LBS - absolutely necessary unless you enjoy stopping every 5 minutes to put chain back on the chainring.



    Now let's see your setups and tell us why you chose your components.

    How About 1x8?

    44T chainring and 12-25 cassette all Campy drivetrain.

    I had to run it 1x for a while while I was waiting for replacement chainrings. Middle rings are tough to come by. It wasn't much of a climber but but it was a good warm up for cyclocross (ie having to run up steep climbs).

    44x25 low gear?

    Wouldn't that rub bad?

    just looking at that makes my knees hurt.

    Not That Bad

    It's on par with the gearing most of the SS crowd runs.
    44-25 = 1.76:1
    2:1 is fairly standard SS gearing

    What do you mean 'rub bad' ?

    When you're in the big ring in the front and back; it usually stretches the chain to the max and creates an extreme angle across the gears. It wouldn't be as bad with a 25T in the rear as it would with a 32T.

    Well Technically....

    ...it would be the same. The 25T and 32T would be in the same position on the cassette body so the angle would be equal.

    However I ran a shorter BB temporarily with the single ring. This shifted the 44T in where the middle ring would be therefore giving me a pretty good chainline and allwing the use of all 8 cogs.

    I went 1X9 a while back and love it. 05 Specialized Enduro Expert...

    Extralite 30T CR
    Spot Brand Ringguard
    N-Gear Jumpstop
    XT Cranks (tuned)
    XT Med Cage RD (Tuned with Ti and XTR parts)
    XT 11-34 cassette
    Sram PC-99 chain
    Crank Bros 2xTi pedals
    Answer Pro Taper carbon riser bar
    FSA XC115 stem
    ODI Oury grips
    LX shifter pod (tuned)
    Juicy 7 brakes (stock)
    Chris King/Mavic 819 wheels
    Fox 36R Talas (stock)

    new rear shock should be in the mail (DHX Air) because my 5th Element died this past weekend

    everything on my bike was chosen to reduce weight or increase strength. i weigh 200lbs and ride hard, but climb LOTS. going up then going down is what we do so, light to go up, strong for fast hard decents. i freaking hate FD's and i hate trying to tune them. besides the frame looks so much cleaner now. i only own one bike so it has to do everything for me.

    That's a sweet setup. What's your total weight?

    she is still a bit heavy depending on tires. just above 30lbs with Kenda Cortez 2.4's. she is a bit heavier right now with a Kenda BG 2.35 on front with a Maxxis High Roller 2.35 UST tubeless on the rear (don't know exact weight).

    i could drop more weight by milling/drilling the ring guard or tuning the right shifter (i did a bunch of grinding and stuff on the left one that came off as an experiment and lost 60g or so). the seat is rather heavy as well as the grips, but i sort of like their functionality. longer seat lets me move my weight around on the climbs and the grips have a really nice solid feel to them.

    i like your setup too. i would probably have a lot of pinch flats if it weren't for my 6" of rear travel though!

    i do hope to build a new bike this year. i hope to get a 29er (with full gears) for when i ride with the cardio freaks. it seems that riding with those guys with this bike is a bit of a handicap they all have carbon framed super light fully geared XC machines. needless to say i struggle to keep up with them on the climbs and fire road ascents. (i make up some time going down though)

    Been riding this for over 2 years now. I've only dropped the chain a handful of times and it has always been in a crash, never while riding.

    Forgot to mention 36T non-ramped chainring, 11-34 cassette. I live and ride in Colorado and have never run out of gears. Love 1x9 so much that I've convinced my friend to convert on his new build.
    Happy Trails...

    Deore shifter
    SRAM PG 960 11-32 cassette
    SRAM PG 960 chain

    Heres my 05 Cannondale Prophet. I upgraded my crankset to the Shimano XT and decided it was time to give a Bash gaurd a try, while I was at it i took the Front D of and ditched the granny ring figureing it was time to get strong. The bashgaurd has allowed me to do a lot more, it is so fun to crash over large logs. The plastic E.thirteen slides ride over the logs, very cool. So far i have been doing allright without the granny gear.

    I used the Jumpstop, the the chain has held on pretty well

    I have a SC Superlight 1x9 with an old Raceface taper crank and Spot 34t ring, don't use a Jump Spot and chain drop has not been a problem on this bike for almost 3 years. My old heckler needed the JS or the chain would not stay put.
    Really like the extra ground clearence and clean look of 1X, and I never used the big or small rings anyway.

    Loving' the 1x Set-Up!!

    I converted my Chester to a 1x8 set-up. Removed the smallest cog from the cassette because the Boone chainring I am using was built to sit in the 'outer' ring position and by adding a spacer behind the largest tooth, I was able to improve the chainline. My Smoothie is set-up as a 2x9, likely to also loose the smallest cog to lessen the cross chain effect. Here's the complete build.

    Matt Chester Frame ( I believe the only vertical dropout Ute he ever built)
    Fox Vanilla RLC fork
    CK Ti headset
    Moots Ti Seatpost and Riser Bar
    Seven Cycles Ti stem
    Wheel set (f) Phil Wood Sl disc hub/supecomp/Dt 4.1d
    (r) CK Classic/supercomp/Mavic 3.1
    Phil Wood Ti BB
    Avid BB-7 (f) brake Avid Ultimate Vee (r) with Avid Ultimate Levers
    Boone Ti SS Chainring (31-tooth)
    Cycle Dynamics Ti 13-34 cassette
    RF Turbine Cranks
    X.0 Rear Derailleur and Twist Shifter

    Hands down, that's got to be the most beautiful bike ever to run 1x9.
    Awesome.

    Here's mine. It's an '05 Voodoo Bizango. I picked up a 32T salsa chainring from my local REI and got an NGear jumpstop, and I got a bashguard off of ebay. I run a 11-34 cassette. It rides like a dream and since converting it 9 months ago it's been maintenance free. I hated that front der.

    wow.. both of those last two are very beautiful bikes. nicely done.

    MTB dad... i can't believe that you don't have problems dropping the chain, but whatever you did to keep it in place, congrats. it is so sweet and clean without the N-gear. do ride hard through rock gardens and such?

    I am running a...

    jump stop, just not the guard. The chainring is a Boone SS ring, so it is unramped and the teeth appear to be slightly taller than a 'standard' ring as they were never designed to allow for the chain to move. The removal of one cog and the subsequent moving of the rest of the cassette 'outward' seems to keep the chainline pretty straight. I don;t ride a lot in the way of rock gardens here on Long Island, but we do have our share of root gardens that will chatter your fillings loose and knock wood (knuckle to head) no issues yet. The RD is a medium cage and I run the chain as short as possible. In the process of planning my next 'project' which will be another 1x8, probably a softtail.

    i too run the med length RD with a pretty short chain. i bet that boone ring helps lots. anyway you have a super sweet bike! thanks for posting pics.

    i am actually thinking maybe my next build should be a 1X9. i am looking at getting one of the Niner S.I.R.9 frames. currently agonizing over color and fork choices

    Boy there are some nice setups in here! Kind of making me wish I had set mine up as a 1x9 instead of a 2x9. Maybe that will be a project for next winter..........

    so i asked my LBS to get the pricing for my next potential 1X9. the S.I.R.9 in red. i want to do a red/white/blue theme. blue king hubs, red spoke nipples, red frame, red/white/blue king headset. i need to find more white parts and maybe some more blue bits (might have to look into getting some custom colors on the fork )

    originally i was thinking that i could ride the 29er as a full geared bike, but i have been riding the wifes bike (05 stumpy with full compliment of gears) and i don't do well with the granny gear. even on the looooong steep climb called "Cardiac" i ride better in the middle ring than when i try to spin the granny gear. maybe it is due to riding my bike 1X9, maybe my physique isn't good for spinning.

    initially i will build it up as a SS and add the gears when money is available.

    Lesson Learned vis-a-vis Tempting...

    the fates! Dropped the chain for the first time this weekend after proclaiming so authoritatively here that I have no probelsm with chain drops. Oh well, I guess I'll just keep my big mouth shut!!

    that totally sucks! i am sorry that i had to go and jinx your perfect record. your bike is really pretty without anything on the outside of the ring. a quick fix would be to throw a Spot Brand ring guard on the outside. the best fix for you would probably be a device similar to what was shown previously where the jumpstop captures the inside, top, and outside of the chain. a nice AL billet piece might not take away from your aesthetics too much.

    mtbr provides all of its members with space to store bike photos. near the top of the page there is a link "upload photos". your image needs to be within the size limit (250 kb). click the "browse" button to upload the pic from your hard drive to mtbr. then click on the pic in your gallery, copy the image url, and use the forums image code. for example:
    Code:
    if you already have the pic up on a website somewhere, you do not need to do this. just copy the image url and use the forums image code (you can also click on the small picture of a mountain and sun above where you type, if you don't want to enter the tags manually). make sure you click the "preview post" button to make sure everything is ok befor you submit your post.

    an alternative way to upload files (usually pictures), is to click on the "upload images" button in the "attach files" box. this is located below of where you type. easy as pie. eating pie i guess. i couldn't make a pie to save my life.

    two question: 1) where did you get those low profile chainring bolts, and 2) where did you get that chainring roller guide, or is that scratch built

    thanks

    The chainring bolts are standard BMX equipment (any LBS should carry them). I have seen them also advertised online as "single speed chainring bolts."

    The chainguide was something I just scraped together with stuff I had in my basement junk hardware box, but it was inspired by a post that used to get a lot of talk here a few years ago. Some guy took some coins and made one that admittedly looks much nicer than mine, but mine was origionally intended as just a prototype (some prototypes last longer than others). Anyway, I had the benefit of having an "e-type" derrailleur bolt to fasten the chainguide to, but you should be able to easily alter one of those "jump-stop" thingies to function as the anchor to the seat tube.

    Think I found the pic that inspired me awhile back (sorry I don't recall who origionally posted it, so I can't give credit).

    buff, i've got to make one of these...i like the fact that it is on top of the chain as well as side to side some what..i think i loose chain because the chain can rise up..but this overhead deal should keep it put...it would be interesting to also have one at the 6 o'clock position..but maybe that's overkill...but man, i jump and smack into stuff and blast through rocks...invariably loose the chain in these situations

    i've gone to my local lbs, the guys is older and doesn't know or care, keep telling me i come in asking for these he doesn't have...i though lbs guys loved bikes and how to solve problems with them

    anyway, thanks...maybe i should just get an MRP LRP

    I'm a huge fan of the "Keep It Simple Stupid" philosophy! I guess I don't see the need for all these bashrings AND jump-stops. I have no doubt that this method retains the chain, but it just seems like such overkill to me. Seems ridiculous to add so much stuff just to "simplify" to a 1x9 drivetrain. Don't get me wrong, if you live in an area where you tend to chew up your chainring, by all means use a bashring. But if you are just looking to keep your chain from coming off, there has to be a simpler way. Heck, before I constructed my little chainguide, I just used my regular ol' front derrailleur with great success (maybe it doesn't look as cool, but it worked flawlessly and had so much less......I don't know.......crap).

    Basically, I just don't understand how most of the general population runs 3X9 with a 42T or 44T chainring and doesn't destroy their chainrings, but when you go to a single 34T or 36T chainring suddenly everyone needs a bashring!? Is it just me or does this all seem like overcomplicating matters?

    I absolutely understand that some people's riding styles require bashrings....I'm not saying nobody should run one. I am just asking how many people are running bashrings combined with jump-stops, just to serve the purpose of chain retention.
    Happy Trails...

    i think the idea of jumpstop and bash ring, is that the chain cannot derrail to the right or the left...i just mounted a jumpstop (without bashring) and i lost my chain a bunch coming down my favorite fireroad, the chain came off to the right as you'd expect. waiting for the bashring to show up at my doorstep, this bashring should hopefully elimanate the loss of chain. but your set up is very simple and cheap...so my bashring and jumpstop will eliminate left and right movement of the chain, but the chain can still rise up and possible over either the bashring or the jumpstop.

    i will find this out shortly...your systems prevent almost all movement of the chain, which is nice for such a simple design...need to be in thinking mode over buying mode

    Doesnt for me.

    Despite the fact that I love my 1x9 bike, I still think the N-gear Jumpstop is way too fragile. I've already broken 2 of them. They're made way too light. I wish they would have added a little more material on the thing.

    i just got one set up on my bike...where did yours break? same way? and could you figure out how they broke?

    I don't know how it happened, but one time the plastic broke and the other time the metal bent in a way it couldn't be bent back again. It happened during freeride applications.

    I do run a single speed specific 32T chainring by the way.

    But the jumpstops are so damn cheap, I will keep ordering them. I just love the 1x9 simplicity. Front derailleurs are satans work.

    as far as having a ring guard, it is essential on my bike. i will see if i can get a picture of what my spot brand ring guard looks like after 5 months. it is pretty beat up. i do play around on boulders more than most people i guess...

    Yeah they are, they make noise, and are a pain in the rear end to adjust

    but they are a rudamentary chain guide...if that's all ya got

    The point I was trying to make is that lots of people appear to be using a bashring for the sole purpose of keeping the chain on their 1x9 setup. It amazes me that no mainstream retailers have come up with a simple retention device that would save lots of weight and just look so much cleaner.

    weird, your reply appears above mine instead of below it (where it should be, since i have posts linear, oldest first).

    i have a second question for you 1x9'ers - the chain is angled quite a bit when using the smallest and largest cogs, how does this affect drivetrain wear? granted, it's not as bad as the small-small or large-large combos in 3x9 setups, but....just wondering out loud.

    Most of us are using the middle chainring position. Unless you've altered the stock chainline in some significant way, the middle chainring is usually designed to be able to reach all the rear gears without severe chain deflection.

    I completely understand your hesitation with regards to premature wear. I considered that before switching. Much to my relief, I have found that there has been very little difference in chain and cassette wear. I have seen no difference with the largest cog, but do see marginally more wear on the smallest cog. I chalk this up to excessive use more so than the angle of the chain. Realize that you will run that 11 or 12 cog far more often than you used to with a large ring available. I never used to run a small chainring, so I actually do almost all of my rides in the smallest 7 cogs (the largest two have simply become fallout gears). That could also explain why I have not noticed any additional wear to the large cog. To clarify, I run a 36T chainring with 11-34 cassette.

    i havn't noticed any severe wear on my drivetrain. i do keep up on my maintenance though. every week i make sure i clean my chain and relube it. i use mineral spirits and my air compressor to thoroughly clean the chain and then relube. i do a lot of climbing and spend quite a bit of time in the 34T cog. i figure if i had a XTR cassette the Ti cog might wear faster, so i stick to XT. I run an Xtralite 30T chainring.

    my Spot Brand ring guard does a great job of protecting my chainring. it isn't as beefy or as heavy as the big bashrings. it doesn't weigh much more than a stock XT big ring. it does perform double duty keeping my chain on, but primary duty is to keep my drivetrain working.
