    Build weights with specifics would be interesting to see too especially the Shimano XT kit.

    We just got a size run in at GO-RIDE.com. They look awesome. We ordered the black with blue accents to match the blue ano parts and the blue accents on the Fox suspension. I'll be building one for myself, but I'm still gathering a few parts. Here's a couple of phone pics.

    The large and medium are already built. The frames come with the headset cups and the bottom bracket installed. We didn't want to press them out to get a weight. I'm building a small for myself. I'll try to get a weight on that.

    I'm 5'8". Last season for Enduro I raced a Yeti SB66 in Medium (24.1") ETT. I mostly used a 50mm stem. The 50mm was a bit short for true XC riding, but perfect for Enduro. Overall I prefer a 23.5" ETT bike with a 70mm stem for most riding and then a 50mm for more aggressive Enduro events. There are three reasons I'm going with a small on the 429c. 1. It has a 23.0" ETT on the small which I can run a 70mm and be good for XC or Enduro and a 50mm for aggressive races. 2. The seat tube on the Medium is too long for me to run some 5" dropper posts. 3. I like smaller wheelbase 29ers. I find the longer wheelbase of Medium 29ers to be less fun on jumps and tech trails.

    Serious Dude Night...

    Loving Wife out of town...
    Sci Fi on the Panel...
    New Pivot 429c Semi Custom Build In the House...literally

    429c carbon thread-img_0429_0329.jpg


    At this point I am seriously enamored with this bike...unbelievably capable and balanced, ruthlessly efficient and *very* fun transition and air capable. Rode Palm Canyon and the bike performed flawlessly. Setting PRs left and right...

    I have put ~100 Miles on it and changed out the 2x10 for a triple with a 22... more on that another time, but its the right choice for my riding habits.

    Trail Build...5.10" Medium , 70mm Stem (may go 90x10) XTR / XT mix, triple, 240s w Stans Arch ~27lbs.

    fwiw- build weights can be approximated on compxxx-cyclist dot com.
    curious to know what you pivot heads think about a 429c conversion to 650b. yeah, I know about the bbh/pedal strike potential. maybe I should ask the 650b forum folks, but you guys are closer to my fingers. so there. TIA

    I'm used to riding low bikes (many years racing DH) and use 170mm cranks. I've been having a few pedal strikes on my 429C in technical climbing areas with 2.35 tires. With the much small 27.5 you would be hitting your feet a lot unless you ran zero sag.

    My medium red/black arrived back on Dec 12, 2012. In Australia we got the XT/XTR build instead of straight XT. Also the DT Swiss set up was switched out for Stans 330's and Arch Ex rims due to the supplier marketing those products.

    Have switched out the std stem and bar for a -16 degree 90mm specialized stem I had lying around, and a 650mm alloy flat bar to get me into a better riding position, not a fan of wide bars...yet. Tires changed to ones more suitable for our trails, NobNic front and RaRa rear, also went tubeless.

    Have also flipped the shock around and added some washers to the inner triangles cage to allow for a normal sized drink bottle to fit without rubbing on the frame. Also a normal sized bottle doesn't fit underneath the frame without interferring with the compression of the front forks.

    Weight is 12.41kg.

    Large XTR Lefty carbon

    Just picked it up from LBS after swapping out my old frame.
    23.8 lbs as shown for a large. No flexy weight weenie parts.
    Loved my 2011 alu 429 but couldn't resist the 1lb weight savings, additional rigidity and slightly quicker handling of the 429c. 2011 large 429 (alu) frame is for sale BTW

    First ride tomorrow morning. Woot.

    Beauty! Looking forward to the ride report. A couple of questions: which lefty are you using, and what is the final a2c once if you made any mods? Also, what is that mount on the top tube?

    Cheers!

    First ride 2013 Large Pivot 429C impressions

    26.4mi, 3577 gain'. Jeep trail and singletrack, damp hard pack, lots of embedded rocks. Ran 12mm of sag, otherwise exact same setup as 2011 429 alu that we just switched from.

    I've done lots of bicycle and automotive R&D so try to go in not thinking about the bike. Just ride and let things surprise me. Overall, the bike is incrementally improved in several areas. No huge differences.

    Handling
    It was hard to notice the shorter chainstays. I could feel it was a little easier to manual over rocks when descending. More noticeable when pumping tight radius bermed turns. Part of this better tight radius handling was the lower BB. Stability was stellar with the alu frame so the carbon didn't have much to gain. Felt like it tracked a little better during forceful direction changes at speed. Definitely stiffer torsionally but not night and day. Most of the torsional stiffness gains seem to be in the back, despite the tapered HT and general beefiness up front. Maybe I imagined that

    Shock performance
    Probably the biggest difference between the 2011 alu 429 was the new CTD shock. Climb - Trail - Descend. Riding it, you can tell the low speed compression damping increases as you click towards climb but it's the high speed compression damping difference that stood out. The 2011 bike would kick a bit when smacking 2-3" embedded rocks at high speed. The CTD on "D" soaks them up almost completely. Big gains there. What was a surprise to me was how well it climbed in D. The softer low speed compression allowed it to react quickly to little embedded rocks while climbing seated at low speeds (4-8mph). The only time I really wanted the Trail or Climb damping preset was on the paved ride to the trail head or if I had a long out of the saddle climb on smooth fire road. IOW, I ran D setting for pretty much the whole ride. What was also nice about the D setting was it's better absorption of those 2-4" ledges when you have to deliver a brief 500w burst and trials/crawl over stuff. If you have ever climbed on a triple chainring 6" bike you know what I'm talking about. Get a little momentum and the stuff that stops most short travel XC bikes doesn't phase the 429C with the shock on D, almost like 6" bike.

    Shifting
    I didn't touch the drivetrain after the shop gave it to me. The old frame had the special Pivot e-type FD mount. The 429C uses a direct mount FD. It wouldn't shift to the big ring under full power, half power or less was fine. Nit picking I know but the old frame would do it at 400w+. I'm gonna guess it just needs some adjustment and won't proclaim that as endemic. I also got a few derailleur slaps in the smaller half of the cassette, which I didn't get with the old bike. XTR shadow long cage. Once again, I'm going to guess it just needs a little adjustment love.

    Fit
    Within seconds of rolling out I noticed the lower BB. Well, I should say that the bars felt high. I wondered what the shop did then the lightbulb went off. They matched my old BB to seat measurement (very good shop) but the new BB is a few mm lower. Suprised it was so noticeable but I definitely like it. Others here mentioned catching pedals but I never did. To quantify that, I run 180's Egg Beaters and pretty much pedal through everything.

    Climbing
    Again, the old bike was awesome so not a ton of room for improvement. I did notice the rear tracked better when seated powering over rough stuff in a low gears. I put that down to the new rear end and 142mm through axle. I didn't expect that so it was a pleasant surprise. The next I'll say is that it just seemed to be a few watts more efficient in every climbing scenario. More than the some of it's parts in this case. Definitely goes up hill and pedals just a wee bit better and I'm not I fully understand why. Don't care either, just reporting the impression.

    Would I do it again? You bet. Besides, more carbon is always better.

    Update: Few minutes trailside adjusting dialed in the FD. Perfect full power up and downshifts. Now to see if I can do something about the derailleur slap.

    Also, I have a suspicion that these early production 429C's are not significantly lighter than the 2012's. There was mention in early press previews that the preproduction samples were purposely built heavy. I only lost .4 lb, same build except the direct mount FD and DT 240 142TA swapped from a Project 321 QR135 and my old frane was the heavier 2011 model 429.

    Rider: Twenty-years on mtb (6 on 29ers), former BMXer, based in Northern Virginia
    Weight: 220lbs
    Height: 6í4Ē
    Inseam: 36in
    Sleeve: 37in

    After last summer, I decided to put my six-year old Ventana El Rey out to pasture and update my ride based largely on geometry data due to a general lack of XL bikes to test ride. Having ridden a few bikes with shorter chain stays, I knew that I wanted stays shorter than the 18.3 ones on the El Rey, and I also was keen on finding a bike with a lower bottom bracket. After months of research, I pre-ordered the 429c from Competitive Cyclist in November and just took delivery of the frame the first week of April.

    Out of the box, I was incredibly impressed with how light the frame felt; easily a couple of pounds lighter than my El Rey. What didnít impress me was the lack of internal cable routing, which I didnít know was only featured on the smaller frames. Still, cable routing alone wouldnít have swayed my decision and as I tell my four-year old, ďYou get what you get and donít get upset about it.Ē

    The build was pretty straight forward as I was mostly porting over components from my older frame, and in hindsight, not having to fuss with internal routing, probably made the process a tiny bit easier. One thing that did stand out was the front derailleur; it was stupid simple to install. Whoís to say whether or not front derailleurs will be around in a few years, but while they are, direct mount is definitely the way to go.

    To date, Iíve only gotten in three solid rides on the 429, but Iím really loving it. There was initially some concern about choosing a 34 as opposed to a 32, fearing that it would rake the bike out too much, but that isnít the case at all. Set at 130mm, the 34 brings the bottom bracket up to only 13.5in and slackens the head tube to about 69 degrees. This setup is spot on for the Mid Atlantic, where roots and rocks cause pedal strikes with lower bottom bracket heights, and, to boot, it feels very comfortable.

    Thereís not a world of difference in terms of stiffness compared to my El Rey, but that frame is a tank in comparison, and I feel that the DW link suspension does provide much better pedaling efficiency. Looking down at the shock as I climb root and rock strewn trails, the back end gently absorbs and erases much of the harshness. And, when pedaling on the flats, thereís no discernible movement, even in the ďtrailĒ setting, which is where Iíve set both the shock and fork.

    Once I get more time on the bike, Iíll post a longer report, but thanks to everyone here for advice and build tips, and also to Pivot, who offered fantastic customer service throughout my wait. The 429c, so far, has been time and money very well spent.

    I tell my two... "You take what you get and you don't throw a fit, or you'll go to your room and that's where you'll sit!" They love to quote that back to me when I tell them they didn't clean their rooms well enough.

    gorgeous bike. looking forward to more ride reports on your build.

    Great looking bike. The only "flaw" is the stanchion on the right side of the fork!

    Anyone riding a shorter stem on their 429c? I was running a 70 mm Thomson, but I wanted it to flick a bit more in and out of turns. Just threw a 50mm Thomson on and was curious to see if anyone else had done this. Oh yeah, I ride a enve 9d sweep flat bar.

    This is my new build. Don't have it dialed in just yet (Need to cut the steer tube after I get some trail time in), been to busy at the shop. So far, looks good. Not a feather weight, but respectable at 24.5 lbs for a Large.

    Funny for me the 70 *is* the short stem, I find it very responsive on my medium, I am 5'10". Let us know how the 50 works.

    I finally got a few rides in on the 429C. I am very pleased. My initial thoughts is it descends and corners better than any 29er I have been on. I am shocked how well it carves. I haven't got to test it on a hilly techy trail yet but I will on Thursday. Someone mentioned that it is very neutral. I would agree. It feels like a MTB should, be never does. I notice I clear sections much faster than before. Its almost like cheating. More to come...

    see any issues with 6.4/235lb behemoth on an XL carbon with 34 talas fork ran at 110mm.
    will a Chris King Insert 2 tapered headset be fine?

So I was set on thinking that 29" wheels were for big guys. After looking at your pic of the small framed 429C I might just have to give this bike a shot.

    Why would I choose a 429C over say a Ripley? What would be the compelling characteristics?

    Google "pivot 429 vs. Ripley". I read a geat comparison of the two the other day. Counter intuitively, they chose the Ripley for more of an XC bike and the Pivot 429c for a better trail bike. Good read...

    I chose the 429c because the ripely was way too small. The Ibis xl is equivalent to the pivot L.

    Anyone else have their compression dampening on their Ctd factory shock blow up shortly after getting their bike? My shock only lasted 8 hours.

    I've been running the shorter 50mm stem for a few weeks now and here are my thoughts.

    My other bike is a Niner MCR with a 50mm stem with a 100mm fork. This bike is insane in the twisty-turner stuff. When I first got it, with a 120mm, it was great in big sweapers, but pushed a bit in tight turns. When I had the fork pushed I dropped it to 100mm and added the 50mm, now it is one of the most nimble and quick bikes I have ever riden. I know this is not the pivot, but I am providing some more background for comparison.

    So now when I first got my 429c, I felt it pushed a bit and was slow on the turns. Not enough to be bad, but enough to make me notice. With the 50mm stem, I find this to be less the case. I certainly need to be much more careful on the line I take through a turn, but it doesn't really seem to push much. I think it is a better setup for me than the 70mm.

    The one negative I will mention though. The front end tends to get a bit light on really steap climbs. With the 70mm stem I thought the climbing on this bike was beyond the best I had ever seen. With the 50mm, it can get light but it is still really good.

    Final thought, the improvement for me of the 50mm stem on flats and tight turns far outweighs the occasional lightness I get on climbs.

    You can sometimes pull the bushings apart by hand but not very often. The bushings on that shock consist of a sleeve that fits through the tan colored inserts in the shock body. The sleeve then has 2 spacers with tiny dust-seal o-rings, 1 per side. I have a tool for doing the removal but you can use pretty much anything that is smaller in diameter than the spacers. It's fairly easy to tap the sleeve out enough to remove one spacer and from there I've been able to pull it out by hand. You don't have to remove the tan pieces so that makes it a LOT easier. You'll want to use something like a deep socket and be careful not to mar the sleeve or deform the end (kinda hard but not impossible).

    600 miles in starting to getting some creaking...not seat / seatpost. Down below.. I will begin the hunt but also would appreciate any insight if anyone has any. BTW...still absolutely enamored with this bike.

    I started to have an odd noise as well at about the same mileage. I tracked mine down to a rear hub issue. It is tricky in that it seems the carbon frames resonate any noise and that made for more investigation than usual. Took me a while to pinpoint the culprit. Made for a few rides of me scratching my head and watching and listening to
    the bike instead of the trail. Good luck.

    34/130- warranty?

    [QUOTE=jaredbadams;10306527]Bike setup: Pivot 429C
    Frame Size & Color: XL Carbon/Blue
    To date, Iíve only gotten in three solid rides on the 429, but Iím really loving it. There was initially some concern about choosing a 34 as opposed to a 32, fearing that it would rake the bike out too much, but that isnít the case at all. Set at 130mm, the 34 brings the bottom bracket up to only 13.5in and slackens the head tube to about 69 degrees. This setup is spot on for the Mid Atlantic, where roots and rocks cause pedal strikes with lower bottom bracket heights, and, to boot, it feels very comfortable.

    Do you know if using the longer travel fork voids the warranty. I know Pivot wasn't specing these on the builds. My only gripe with my 429c is on steep fast rocky terrain the front end feels a bit short with the 120 float.

    429 carbon thread

    According to Pivot customer service, the 34 at 130 won't void the frame warranty. I'm on the larger side, appreciate the added stiffness of the 34, and would recommend it if weight isn't your top priority. Here's an updated picture 429c carbon thread-image.jpg

    I'm around 240 with a 35in inseam. I don't think Pivot rushes their bikes to market and self promotes a product that is developed for 85% of the riders out there. If you ride 4-5 times a week and like the chunky trails, I say go for it. FWIW, I now prefer Cane Creek headsets.

    hi again, has any of you experienced "click" or "tick" sound coming from the linkage of the suspension when pedaling hard off the saddle?

    Check the rear axle. Loosen and re-tighten.

    creaks and ticks

    Yes,

    Like a few here I am hearing the same creaks and ticks. Started about the 500 mile mark.

    Pulled a few things apart and cleaned and lubed. Helped a bit, but came back.

    What I have found is that when I wash the bike and have it clean, it's dead quiet for a few rides until it gets dirty again. So, at this point I'm assuming it's dirt, or dust, something that gets in there and creaks.

    Also thought it could be the cable ferruels on the rear chainstay for the rear der. Light coat of grease on them.

    Ultimately, it's something dirty or not lubed. I don't think it's structural, but also will admit it can be annoying. I would love to figure out the root cause as thus far I've thought it was the rear wheel dropouts, possibly the linkage, or even my seatpost.

    I of course didn't just try one thing at a time to narrow it down.

    I cleaned it before a 4 day trip to Colorado. Dead silent day one and two. Day two was a 5 hour epic with lots of crapola. Next day it creaked like a MOFO (I cursed the creaking a few times, but absolved it for the great ride).

    Got it home, washed it off this AM - Dead silent again.

    It's my only issue thus far as I love how the bike rides. But, with 4 kids I don't have time like I used to to try and really narrow it down to the root cause - so if someone figures it out - let us know!
