    TwoNin9r's Hammerhead Thumper Build Thread

    Hello all. I hope you all enjoy this build thread. This build came about as i read the "do we really need all that ravel" thread. It got me thinking that a longish travel 29er would be a perfect sled for my local trails. so i started stringing thoughts together, some coherent, some ridiculous. Here Goes:

    The frame is on the way. as it shipped today, actual pictures of the frame will follow. The fork will be in in about 2 weeks.

    But it's time to get to work!

    as i've sourced parts for this build from my existing bikes, here are some photos of the donor bikes. (note: i have mismatched wheelsets on the F29 and Inbred ebcause i hadn't laced the Arch hoops to the lefty hub in front yet before deciding to go for this build.)

    Donor Bikes:
    '12 Scott Spark Pro 29er. this is where the components will come from primarily, save a couple things here and there, and the wheelset, the frame and fork will be for sale.

    The Inbred SS 29er. the whole bike is going for sale (consolidating)

    Stand by!

    Got started with the build. here are a couple shots

    Here's my driveway set up as my workstation, with my build partner... of course

    DSC_2065 by TwoNin9r, on Flickr

    the frame, in XL, weighs in at just over 7.4 lbs with the Maxle

    DSC_2073 by TwoNin9r, on Flickr

    Rear wheel installed

    DSC_2079 by TwoNin9r, on Flickr

    Rear Der., cassette, and wheel

    Closeup

    DSC_2082 by TwoNin9r, on Flickr

    This stuff is AMAZING!

    DSC_2078 by TwoNin9r, on Flickr

    As it stands, this was all i could get done. I'm waiting on the Fork to come in from Scott at Switchback, i'm waiting for my Front Der., cranks, and tires, to come in from the bike shop, waiting for the Handlebar to come in from amazon, and i'm waiting on my seatpost to come in from pricepoint. Lots of waiting to be done, but all in all, i should be able t get her on the trails this week. i want to figure out a way i can carry my DSLR and my hydration pack in the same backpack, but i see the consequences of any type of malfunction being catastrophic, pics and ride report will definitely come soon, though. in the meantime, feel free to comment.

    Some random pictures from ride number one:

    disclaimer, i put an old 175mm XT crank i have on for the ride, along with a random parts bin saddle, seat post, and handlebar. the finished bike will have black 180mm xt cranks, truvativ boobar handlebar, easton haven carbon seatpost, and chromag trailmaster saddle... use your imaginations until the next update

    getting ready to ride

    My top secret way to prevent chain slap, since i haven't gotten a chain-stay protector yet... i'll never tell what it is... and there's definitely no evidence in the photo...

    DSC_2086 by TwoNin9r, on Flickr

    trailhead, ready to roll!

    DSC_2096 by TwoNin9r, on Flickr

    No shame in repping this hammerhead!

    DSC_2102 by TwoNin9r, on Flickr

    and after the ride... back up on the wall preparing for the final build parts to come in.

    DSC_2108 by TwoNin9r, on Flickr

    until next weekend...

    Thought you might like this:

    From the first weekend of field-testing the Prototypes in Deer Valley, UT

    After 3-days of chairlift runs a friend of mine bet me $20 "it doesn't climb good"
    We were waiting for the next lift ride and standing at the top of the stairs down to the locker rooms.

    The $20 came down to him betting me I couldn’t climb stairs on it…..if you haven't climbed stairs on a bike before....it's an awesome way to see how well a bike will climb in technical situations!

    https://www.dropbox.com/s/gy1ls8nf8d...Stairclimb.mov

    I took the $20 in product from here Wasatch Brew Pub & Brewery - Park City, Utah

    I'm very strongly considering it. I never even would have thought of one until I started reading this forum, but I don't know if, with the style of our trails, I can justify the cash for a dropper. South Florida is weird. If I could find a good used one for an absolute bargain I would try it out.

    Is that a custom color on the 130X? How was it priced compared to the $750 Thumper?

    If I'm not mistaken, Scott has a couple of each still for sale, and I'm sure he'll correct me if I'm wrong, but the going rate for thumper ND 130x is the same.

    There was a brief period that custom colors were possible but it was also when they were full priced. At $750 those babies are a steal!

    The deal to get is the frame/fork combo! I got to ride a Pike this last week and I strongly feel that RockShox has dropped a bomb on Fox. Fox has irked lots of people recently with the CTD forks and the Pike is awesome straight out of the box.

    Mine came with RS revelation xx and it's butter. Really like the feel. Still need to get it dialed in but great things are seeming possible with this bike. No regrets whatsoever on this purchase

    I'm certainly no expert on MTB trails in FL but having visited the sunshine state many times I'm having difficulty understanding the need for a long travel full suspension bike let alone a dropper post. Given the lack of elevation change combined with mostly sandy trails why are you looking for so much travel? Is it that the trails are really rooty? Just curious.

    The park I ride primarily is Markham park. Getting into trails like gun range and crime scene were really really sketchy on my f29. There's also a free ride section in the back with some decent jumps I like to jot every once in a while. A no-no on my carbon 90mm ht

    I was thinking of the same park as being a great place to ride this frame. Have you ridden it at Markham yet?

    I can also see it being a sweet ride at Oleta, Virginia Key and maybe Amelia. Great for Alafia, Boyette, Santos to name some in central Florida.

    Cusco, just curious, what trails have you ridden in Florida?

    Haha just Oleta. I wanted to torture it on dry rooty rocky Ness. Honestly. Great choice in everything BUT the rear tire. I think it'll be much better at Markham. I've never been to vk, Markham will be this weekend. Just got the truvativ boobar 780mm 30 rise and the 180 xt cranks come in tomorrow. All I'm waiting on its the saddle but worst case I will ride with the Silverado this weekend

    Good to see others making great builds from these Thumper frames. The Ano gray frame and welds look the goods in person and Thumper logo looks better than new Switchback logo for me. My build came in at 28# with Flow/Hopes, Revelation RCT at 130 w// 20mm axle, WTB Bronson 2.2, SLX brakes,etc. I bought from another distributor who threw in headset, collar, bb, and adapter with free shipping as well. Hopefully Scott will honor warranty should I ever have an issue. I've ridden a few times here in SoCal and impressions are that the bike is super stiff and stable which I attribute to beefy thru axles and stout tubing shape along with "not too short/not too long" 17.5" chain stays. My old DW link Pivot climbed better, but the Horst link is much smoother descending thru the rough. I find that the stability of this bike allows you to claw up the technical climbs slowly, but surely as compared to a 70 degreeHTA frame that you can motor up climbs a bit more nimbly and twitchy. Like I said before, the Thumper is a beast on the descents - make sure you have good stoppers because it'll blast through the rocks and roots as only a longer travel 29er can. Also, if you really like to flow the corners, pump the berms, etc. a dropper post is needed to get low as you will need to get the saddle in a tall position to climb this bike. Note that 5" dropper may not work on this frame as the seat tube is long as compared with the latest "enduro" style frames that don't employ the seat tube gusset. I have a 3" GD dropper and haven't had issues. Good job on the frame design Scott, and cheers to all those getting a sweet deal on a frame that allows for a $2k complete build!

    Couldn't have said it better. I'm really curious how you hit 28 lbs with a dropper! Nine came in just over 28 with no dropper and xt/X.0/x9 carbon. What size frame is that?

    Thanks. Came across them in a thread on here and ordered them instantly without even knowing what I was going to put them on

    Twonin9r, 28# was as pictured with a 27.2 shimmed Al, 350mm straight post and kinda heavy WTB Pure V saddle. I haven't weighed the bike with my Gravity Dropper, 27.2 3" drop(which are much lighter than hydraulic models)but I imagine around 28.5# roughly as I have a Pretty light Wtb Silverado ass plank. Also, 1x10 loses the FD, cables, front shifter, and 1 or 2 chain rings. Ashima rotors, 120g 50mm custom stem, Al boobar are all pretty light pieces of Kit along with the tubeless race grade bronson tires. Spending just over $2k, I didn't go out of my way for a light build - it just kinda happened. Frame is the 21", so I'd call it XL. So happy that my Satori deal fell through as I ended up with something unique and I really enjoy the shopping/building process as an engineer by day, bike nerd by weekend.

    Sorry, 29r, I meant 29#, not 28. Just realized it, as weight isn't too important to me. My other ride is a 32# Inbred with Marz TST, wtb i19/shimano, etc.

    I'm really enjoying my a Thumper. I've been off the bike for 5 months with a shoulder injury/ surgery so I'm taking it pretty easy but I hit a technical climb this weekend and had zero problem mostly because of the traction this bike provides. I cannot wait until I can start to really push it on the downs.

    I like the vans grips too.

    @okie_calvin - great job on posting that pic! That's the only one of it's kind.

    Yes, it was a "Thumper" frame that we sent to spectrum powderworks for the custom powdercoat and 130x graphics. It turned out awesome....looks even better live.

    Thumper = $750.....That price is slightly below Landed Cost for the frames....clearing them out of inventory to work on getting the 130x frames (updated graphics, exact same frame otherwise) here from Taiwan.

    TwoNin9r's Hammerhead Thumper Build Thread-130x-whtfinal2.jpg

    130x frames will be priced at $999....make a small margin (25%) to help recoup the losses incurred on the Thumper frames.

    This is correct....OG MSRP was $1,499....when the Thumper graphics weren't initially received well, the Spectrum color options was offered up. These were the color options

    Turnaround time was about 4-weeks. If anyone is interested in this option, I can look into it to see if it is still an available option.

My build came in at 28# with Flow/Hopes, Revelation RCT at 130 w// 20mm axle, WTB Bronson 2.2, SLX brakes,etc. I bought from another distributor who threw in headset, collar, bb, and adapter with free shipping as well. Hopefully Scott will honor warranty should I ever have an issue. I've ridden a few times here in SoCal and impressions are that the bike is super stiff and stable which I attribute to beefy thru axles and stout tubing shape along with "not too short/not too long" 17.5" chain stays. My old DW link Pivot climbed better, but the Horst link is much smoother descending thru the rough. I find that the stability of this bike allows you to claw up the technical climbs slowly, but surely as compared to a 70 degreeHTA frame that you can motor up climbs a bit more nimbly and twitchy. Like I said before, the Thumper is a beast on the descents - make sure you have good stoppers because it'll blast through the rocks and roots as only a longer travel 29er can. Also, if you really like to flow the corners, pump the berms, etc. a dropper post is needed to get low as you will need to get the saddle in a tall position to climb this bike. Note that 5" dropper may not work on this frame as the seat tube is long as compared with the latest "enduro" style frames that don't employ the seat tube gusset. I have a 3" GD dropper and haven't had issues. Good job on the frame design Scott, and cheers to all those getting a sweet deal on a frame that allows for a $2k complete build!
    Bike looks awesome!

    Thumper & 130x Pricing

    Also.....if anyone is interested in a QTY purchase....I may be able to get the Thumper frames to you at a little better price.

    I can get the 130x frames to you at a better price.

    "edit" - It is awesome seeing all the positive feedback on the frames and how much everyone is enjoying them. It has been a really great experience as well as a long, difficult experience bringing these frames to market and getting them in people's hands. A big thank you to everyone that has purchased a Thumper frame!

    Thanks, Scott

    Wow! Good job everyone. Bikes look amazing.

    We currently have one in the UK which is being sent around the magazines for reviews/features. Should start seeing a lot more throughout Europe soon I hope!

    I will link any full builds across once we get some orders in and compare a few builds.

    Just started building mine.

    What is the smallest rotor I can run in the rear. I have a 160mm. Will that work?

    Wow. Had the first ride today on wide bars and 180mm cranks... Holy crap I think I'm going to order a second one just so I have it in case the zombie apocalypse happens! Hands down the most fun I've had on two wheels, I was able to ride much harder and fly higher than I have in a really long time.

    Man I really like this frame, nice builds too.

    To the folks asking about this bike in FL... I started riding in FL, then moved to AZ, and now live in rocky PA. There are no crazy uphills or downhills in FL, but there are roots. Lots and lots and lots of roots. And most the trails are built into the side of phosphate pits, so they are fairly technical in places.

    At only 5'10" and 170 lbs and somewhat of a glutton for punishment, I would never see the need for a bike like this in Florida for me. But I bet at the OP's height and weight it would really be nice. Especially at the freeride areas of Santos and Markham. And Alafia/Carter Rd/Razorback/a few others would all be pretty nice to have some travel back there.

    I am very interested in hearing some feedback on these frames for people that live in the NorthEast for sure. I am about a year off from building an FS Trail rig, and this frame is the only 29er on my list.

    You won't be disappointed, and I think you're spot on with the height / weight comment. At Markham on my 90mm travel f29 hard tail, I got tossed around quite a bit. Now, the bike feels like it's on rails through the berms and such, and climbs like no other, but there's no comparison in fun factor, and at about 6 lbs heavier, I still have a bigger smile on my face :-) might even sell the f29 because this thumper set up at 130/130 is pretty much (dare I say?!) a quiver killer.

    I haven't taken it to Markham (tomorrow I will) but at amelia my lap time was actually faster because I was able to use the momentum from the downhills and float over the trail a lot more, also the ardent up front is very confidence inspiring.

    Will report on Markham tomorrow. I'll charge up the go pro and take some video.

    I am just south of you in Maryland. With the crap winter I haven't been able to put many miles on this frame yet as the trails I built this bike for have been covers in snow and ice for the last two months. I did one short ride in the rocks at Gambrill State Park, and I was very happy with how the bike handled there. Since then I have added a longer travel stiffer fork, and put a smaller ring on my 1 x 10 setup. I am looking forward to getting back up there. My initial impressions are positive. This bike is a blast. You can pretty much pick any line you want, and charge it. That said this is my first experience on a bike like this. I spent 2-3 years riding technical trails on a single speed hardtail. I had decent technical skills to start with. Adding this much travel makes it a lot of fun.

    Nice! I am in a similar boat. I have an AM HT and a single speed hardtail and live in Lancaster, PA. Keep me posted how you feel about it as the season opens up.

    I am pretty freaking stoked about this weekend. I plan on riding a LOT tomorrow and Sunday with the recent warm up, followed by the wind I am thinking most rocky trails should be close to accessible. Sorry, not to thread jack, just SERIOUS cabin fever going on in this part of the country. lol

    After a bit of deliberation, i've placed an order for a raceface narrow/wide 34t 104bcd ring to convert the bike down to 1x10.

    further, i'm going to swap the sram carbon brakes and shifters and derrailleurs and such onto my race bike (the f29) and put the full xt get-up on the thumper. the ability to double up-shift should compliment the single front ring very well. i'm also probably going to replace the boobar (at 340g) with a carbon bar. hopefully southing under 200g mark, which will put me at pretty much my exact weight goal for the bike without sacrificing comfort or strength. i will update with pictures as the parts come in.

    29r,

    I hope you like the 34t narrow wide ring. So far, so good with my 30t here in SoCal with some 4+ mile 2500' elev. climbs. Dropped the chain yesterday on a 2' drop, but later realized I had the shadow lever in the off position. I've also got the Boobar 740 wide, 30mm rise. Couldn't pass it up for $25 on Blue Sky. The front does feel a little talk when airborne. I love the confidence of the 130mm 29er on the really steep, deeply rutted downhill predominant here in SoCal. Only thing I miss about my old DW link Pivot Mach 5 is the quickness to spin up to speed, ease to loft the bike and nimble climbing, but on the downs the Thumper is a BEAST!

Dropped the chain yesterday on a 2' drop, but later realized I had the shadow lever in the off position. I've also got the Boobar 740 wide, 30mm rise. Couldn't pass it up for $25 on Blue Sky. The front does feel a little talk when airborne. I love the confidence of the 130mm 29er on the really steep, deeply rutted downhill predominant here in SoCal. Only thing I miss about my old DW link Pivot Mach 5 is the quickness to spin up to speed, ease to loft the bike and nimble climbing, but on the downs the Thumper is a BEAST!
    Great to hear a comparison to the Mach5/DW-Link.....also I checked out Blue Sky to see if I could post the link to the bar in here....gotta help our fellow MTB brethren out if someone may be looking for a new bar.
    Having a hard time finding the BooBar on the site. Do you mind posting a link to it?

    As fate would have it. I decided to lighten up the front end so I ordered CB iodine (same dimensions) carbon (for a 120g savings).

    The fact that you've got the Thumper down to 28lbs with a relatively modest build has me excited that my Unveil7 proto will be similar weight (or less) with a dropper. I'll be running pretty the same setup except Flow's, Monarch+, and Reverb.

    Scott,

    I think the Boobar 740mm sold out on Blue Sky a while ago, but if anyone is content with a 680mm wide bar, Blue Sky has the Truvativ Holzfellet and Hussefelt for $13.

    130x Frames - $899

    The Hammerhead 130x (the updated graphics/name change from Thumper) frames are still in Taiwan.

    If I can get them here and offer a sale price of $899, would that be enticing price?

    Good luck. I went down to 1x10, full xt (including brakes and all of drive train, except for chainring) and it's 28.3 lb. Ordered a carbon bar and I'm gonna go to a lighter saddle as well. Should be around 27.5 lb after that

    Great looking builds here and love the look of the 130x/Thumper. I have never ridden a longer travel bike (only ridden my 100mm Steel Inbred HT and brothers 100mm Rocky Element 5.0) so wondering how this woudl feel differently. I live in the Tahoe area so have everything from fast flowy trail to gnarly climbs/descents and much of it can all be in the same ride. How drastically would it change the "nimbleness" of this bike by going to something like a 100mm suspension (f/r) or 120mm? I know that it was designed around the 130mm+ range but that just seems like it would be a HUGE descending beast that would climb like a fat kid chasing a cupcake. Contemplating a new bike this year and would like to use as much of my Inbred's components as possible to minimize costs.

    I'm set up 130/130 and I think you won't be disappointed. The kashima shock does well not to absorb energy and geometry wise I think the bike does an excellent job of not feeling "long travel" on climbs.

    @TwoNin9r is spot on w/ that assessment. You could also run a Dual-Position fork like the X-Fusion Trace RL2 DLA

    I actually just built a frame/fork package around the Thumper Frame and X-Fusion RL2 140mm fork....$1,299 shipped!
    Hammerhead Thumper Frame/Fork ? 29er | 27.5 | Full-Suspension - Switchback Bikes

    The DLA 140mm/110mm version would only be $75 more

    Thanks, Scott

    Damn that is a good deal, just wish I had the money now. Don't know if I would go with the X-Fusion, never tried one and love my Manitou Tower Pro so much that I would want another one (kinda like our Toyotas).

    I can score this fork Minute Pro 29 120 1.5T Black QR15 Wouldn't be too much more than the X-Fusion package.

    Personally I would go for the Trace over the Tower Pro for anything over 120mm. I had a 140mm Tower Pro for this bike when I originally built it, and the TP at 140mm was very flexy. I swapped it out for a Fox 34 which is much stiffer. Virtually no lateral flex. As for X-Fusion, they make a great fork. I have the Slide on my other bike, and I love it. The Trace gets great reviews.

    Thinking of a slide for my fiancé's 27.5 giant tempt 5. Already threw full slx drivetrain in the and elixir 7s. Carbon bars going on this weekend. Eventually wheelset and fork and she will have a bad little ride.

    Good deal, Scott. Damn good deal if you compare to the XT build Yeti 575 going for $5k that features an inferior suspension design and surpasses Scott's build in just the wheels. That being said, I ran a Crossride front wheel for over a year - stayed true as day one and spun great although a bit flexy with I think 24 spokes. How is it that the Yetis, Santa Cruz, Specialized, etc. folks think the mountain bikers of the world are so stupid to get swindled into a $5k bike or $2k frame when said frame costs them $500 at most. I'm pretty happy with my $220 new Inbred frame.

    If I switch to 1x11, it won't be until the market has a bit more competition in it. Right now sram is setting the price bar high and for what, one more gear? It can be substantial, I agree, but then, I'm 1x10 right now with the ability to go back to 2x10 in under an hour of wrench time. I'm all legs though so I shift probably less than most, I was a park skater ally childhood and that really predisposed me to great leg strength (man if only I had any upper body strength!). So I'm inquisitively spectating for now.

    Scott, perhaps starting a thread titled "Switchback Bikes 2014" would be more appropriate for discussion of such topics as XX1 and the subtle drop of that sweet lookin carbon 29er.

    I want to discuss that bike (and I'm sure others do as well) and I don't want to clutter up TwoNin9r's thread.

    Bump for carbon! Should be installing my iodine 11 bars in the next day or two, I'll take some pics and post them up. Anyone running 780 wide carbon bars? This bar seems too good to be true. Wide enough to really crank on the front wheel, light as hell!, yet strong enough to counteract the extra leverage from the width? And a good price? Haha

    Any reason you didn't go with the RF Next handelbar? Lighter than the Iodine and cheaper too.

    In your defense the 3/4" rise Next is 725mm width, so not as wide as the Iodine at 780mm. the SIXC 3/4" rise 780mm is the same weight as the Iodine 11 and same price.

    Re: TwoNin9r's Hammerhead Thumper Build Thread

    Dimensionally, though, they don't have one that meets my needs. This is likely why it didn't come up as a candidate in my search for a 30mm rise, wide as all get out handlebar. The only 31.6 they have with rise is 3/4 inch rise (too low) and only 725 wide. Also it's listed for xc purposes (among the trail / AM designation) and I'm using the bike as more of a trail bike with lots of rocky descents.

    She's 650b or that would have been done! Lol. I'm thinking of getting a wheelset and just using my stans hubs for her with some crest or wtb frequency, then my lbs will cut the spokes and retread them.

    Not with the carbon bars. Should be mid 27s. Will weigh it probably tonight and post a pic. I'm thinking of going for a wtb rocket v saddle to save another like 120g.

    It was 28.2 at 2x10 with the aluminum bars. Since then it's set up 1x10 and carbon bars.

    Re: TwoNin9r's Hammerhead Thumper Build Thread

    Ah disregard the above post. It was 28.2 in this form


    Now the elixir rs9 carbon brakes and sram x9 carbon shifter and X.0 carbon rear Derraileur have been changed to shimano xt (slightly heavier), it's now got 180 cranks with a single 34t narrow-wide, carbon bars (iodine 11), easton haven carbon seatpost (still pretty heavy) and a chromag trailmaster Ltd saddle (~340g). So yeah I'll weigh it when I get home from work.

    I think this is thing that impresses me about Switchback the most. Scott is selling frames with better shocks that weigh as much or less than comparable big brands for between $500 and $750 less.

    That price difference can go a long way towards a better fork (like a Pike), lighter wheels and carbon components.

    Yeah definitely. My only problem now is how I'm going to treat the fact that the 27.5 is coming out soon!

    TwoNinr are you still in Florida? EDIT: it appears from the pictures like you do.

    For your type of terrain, can you compare living with a 130mm 29er vs a carbon 29er and a steel 29er? Is the extra weight worth the travel for Florida riding?

    If I don't care for 650b and you don't care for 29, we may be able to organize a trade.

    Maybe a set up like this? ($1,000+ less than comparable model from that company you mention above)
    My Size XL 28lbs 12oz as it sits in the pics.....just got it powdercoated "switchback blue" and had some decals made up locally.....working on frame price if something would like to do the same w/ a Thumper frame....The "Switchback Conversion" if you will

    gahhh so many pictures. Sweet color though.

    TwoNin9r, how much do you weigh and have you had any problems with shock tuning?

    I'm 210 in my birthday suit. I set up the fork and shock worth recommended sag, rode it twice, removed 5 psi from the shock and added 5 to the fork and it's been perfect since. My travel ring on the fork is about 2mm from the stanchion after my hard rides. I may be able to squeeze some more travel out of the shock (I get just about a centimeterfrom the end of the body with the ring). I run exclusively in trail mode.

    Nice. Might have to check that out.

    lol yeah essentially (going off of website weights) i could go down about 1.5 lbs with 2 nobby nic 2.25s (have used this setup and actually quite like it for my local trails), a different saddle, and different grips... now, on this setup, i am keeping it exactly as it is, because it's actually taught me that i get just as winded on my Thumper as on my 21 lb F29, but it's nice to know i can go there if i got the "bug"

    so, is anyone else having issues with the site? its not loading correctly and im not seeing any pics or frames for 750

    does anyone do aggressive trail riding on these? i havent gotten to compare the numbers side by side. but im considering getting one of these, or an on one codine... im worried its not going to be aggressive enough for my riding style (obviously the decents, not climbing).

    im not saying im good or even close to being 'good'. i just like to be in the air a lot and am an active rider (move around a lot, etc)..

    I posted somewhere in one of the Switchback threads about my buddy riding his in Sedona and at the Black Canyon in Arizona; I'm not sure what you mean by aggressive enough but my buddy was haulin a$$ and hitting every gnarly line he could for 4 days while there. He's a bunny hopping fool, the bike can take whatever punishment you throw at it; all the big sites (except MTBR) and magazines do their testing there for a reason.

    Pull the trigger, you'll love it! See if you can get the Pike deal still, it's an awesome fork and that was a great combo they were offering.

    I don't know if I mentioned it here but my 21lb carbon hardtail gets no action anymore. I used to think that thing was fast as hell. I did some. Timed laps at my local trails and I'm within one minute on both bikes, but on the thumper I have a smile on for much more of the time.

    I ride mine in Gambrill State Park and the Frederick Watershed. The area is known for aggressive trails with lots of rocks, roots etc. On the Thumper I hit lines I would not have considered before. Mine is built for aggressive riding. 150mm fork, Flow Ex with big 2.4 tires and a dropper post. This bike climbs well, and rips downhill.

    @TwoNin9r - didnt you post in my build thread that you got a KS Lev dropper? How are you liking it?

    Also, what fork are you running... Really starting to think that 120mm is going to be the bottom of the travel I should run with the frame geometry but dont know that I want to go full on 140mm. Hence looking at the XFusion Slide or Trace (both internally adjustable from 120-140mm).

    Not 29r, but I'm running a Rev at 130, splitting the difference, and liking it. As an up and down type of mtber, I'd go 120 before 140, cuz the bike is plenty slack and the handling would get slower/ bb get higher at 140/ wb longer. This bike feels quite a bit longer than my 19.5 Inbred, but the trade off is stability up and down and have climbed some tech that stopped me on my Inbred at 100. Have not felt on top of the front wheel on some pretty steep descents here in SoCal. I'm 6'2" on the 21" frame.

    I'm running a Trace at 140mm on my Thumper and I love it. Not once have I thought that I would like less travel, lower BB and a steeper headangle...but that's just me...

    That is awesome to know because I am coming from a 19.5" Inbred as well where I run a 70mm stem and feel perfect on the bike. I do understand what you mean about the short 100mm travel going over some obstacle or climbing in techy sections. I ride in Lake Tahoe a lot so there is just about everything thrown at you.

    It's not. I have been running a Fox 34 150mm for most of the time I have owned the bike.

    I'd think with relatively long chainstays and a somewhat steep head angle at 130mm, that the bike wont wander very much at 150mm except but the steepest climbs.

    Back when we were all on 26" bikes with 17" chainstays, adding a taller fork made a dramatic change to how the bike climbed, often negatively. I remember having hardtails that I struggled to keep the front planted with only 20mm more suspension up front. Running a shorter stem didn't help either.

    I think 29ers, being longer in general are more resistant to front end wander. Its also what makes them more difficult to lift the front or manual. Those big wheels also turn more slowly, so I think many people prefer to have steep angles and greater fork offsets to retain the quick steering. If you dont mind the lack of quick steering or have wider bars, shorter stem, higher offset forks, I can't see any negatives to a longer fork other than a higher BB.

    Good to know. Slow steering is fine, because it just takes more body english. Not a bad thing in my opinion, well worth the trade-off.

    The bike rides great with a 150mm fork. I ride it on very technical trails with a fair amount of climbing, and I wouldn't consider running a fork shorter than 140 - 150. Getting the front end up and over rocks is easy.

    Do y'all feel it would be neutering this frame to mount up a Fox 32 120mm fork? I've got a Fox 32 120mm CTD FIT Adj Kashima that I don't want to part with. Should put my HTA right around 70*.

    What I like about this frame is: 31.6 post, BSA bottom bracket, 12x142 rear.

    I don't 'need' 130 of squish in the rear (would be just fine with 4.5-5" of travel)

    The closeout price keeps me coming back. I'd be doing a frame swap from a Giant AnthemX 29 (want a little more beef, but don't need an AM bike) with a lightweight XC/trail build (carbon parts wherever possible).
    I like 'em long, low, slack and playful

    If you want a 120mm travel bike, keep what you've got (or go Transition Bandit 29) But if you want something more capable, go for the Thumper and buy a proper RockShox Pike for it.

    Yeah, that's where I'm torn. I've got a 150mm 650b conversion Trek Remedy with an X-Fusion Sweep up front. 66* HTA and angry.

    But I find myself pushing the AX29 a bit harder than I want. And I've learned I should be riding a L frame (not M) for XC/longer rides.

    Oh well, guess this awesome deal isn't for me :-/

    Bit confused by this... I thought the Bandit was also a slack, 130mm 29er AM bike?

    Bandit is 120mm and so your fork will work on it.

    Hokiebrett,

    I think a 120 fork will be fine. I'm using a Rev at 130 and wouldn't go longer as I like the low bb and the wheelbase would just get too long. With a 120 the head angle will be more like 69 than 70. The thumper geo is very similar to an SB95(127mm rear). Check out the Pinkbike review of the SB95. It states that 120 is great, 140 unnecessary.

    Could you fit a 2.4 in back with those Flow EX rims? Or not enough room to run a big tire like that with that wide of a rim? Curious minds want to know.

    I run an Ikon 2.35 on a Flow in the rear. FWIW the Ikon 2.35 looks a bit larger than the Ardent 2.4 I have up front. The Ikon fits fine.
