Scottwrote a review of Pivot Mach 429 Carbon Mountain Bike Frame - 2014 on October 22, 2013
Familiarity: I've put it through the wringer
It goes without saying to never buy a bike based on advertising and hype. Test ride it, compare it and make sure it's what you are looking for. What this bike does is combine great climbing prowess with excellent descending. Flickable for a big wheel bike with confident manners. I demo'd an Ibis Ripley ( full disclosure, I owned a Mojo sl and loved it) and could not shake the short top tube forward feel on downhills, (100mm stem on a large and I'm 5"11). I demo'd a SC tallboy Carbon, and could not get past the feel of the suspension both climbing and descending. I demo'd a Trek Sfly100, great climber, but the long history of breaking dissuaded me. I demo'd the Pivot... Ahhh Goldilocks! For me...YMMV, it was the sweet-spot. Long top tube, short chain-stays, DW link. If you want a full on trail machine you should look for more suspension and give up the climbing ability of the 429C. If you want a cross country racer there are shorter travel and lighter bikes out there. The reality is that there is no one bike to rule them all. You always give up something. The 429carbon seemed to give up less than others I tried.
