Pivot Mach 429 XX
How do you spec the worlds fastest 29er bike? With the worlds fastest groupset!
SRAM XX is a natural choice to match the engineering marvel of the Pivot Mach 429 frameset, and if you want to erase any possible excuses when you're powering along the racetrack, there is no better option than the XX build. Custom DT Swiss wheels keep rolling weight down, and the tunable Fox Kashima suspension allows you to setup your Mach 429 for any course conditions.
When Chris Cocalis from Pivot Cycles wanted to design a full suspension 29er mountain bike he first hit the streets talking to manufacturers, 29er experts and riders, while logging as many hours as he could on different designs so as to better understand the full story. Just about everyone understands the benefits of riding a 29er hardtail though if you don’t know, feel free to ask any staff member at My Mountain as we now sell more 29” hardtails than 26”. But when it comes to full suspension 29ers, bikes can start to become big and clumsy especially under rapid acceleration. It was with this in mind that the Pivot Mach 429 was designed to be the stiffest, most responsive, and fun 29er dual suspension mountain bike possible. A bike that when the pedals are stomped when coming out of a corner the bike and rider are catapulted forward towards the next section of smile-inducing singletrack.
For 2012, the Mach 429 has received some major updates to improve on what was already rated as one of the best 29er bikes on the market. Like the latest Mach 4 and 5.7's, the 429 receives a simpler hydroformed top tube that eliminates much of the welding that was required on the older model, whilst also increasing standover height for more clearance. The rear triangle has been sculpted and machined to remove any unnecessary material, and the addition of a 142x12 Thru-Axle has actually increased lateral stiffness to a level other brands can only dream of. Even the shapely new Tapered head tube has allowed Pivot to reduce a few grams while boosting front end strength. All of these frame refinements on the 2012 Mach 429 add up to drop over 250 grams in weight, which is a significant percentage from what is a super solid bike.
With all this talk of "hydroformed this", "tapered that", you've probably picked up that Pivot have a nutty obsession with frame stiffness, and if you find you have an uncanny ability to turn full suspension bikes into noodles, the short of it is that you are going to absolutely love the rigidity of a Pivot full suspension bike.
From Pivot Cycles:
"The original Mach 429 set the mtb world on fire as the best pedaling 29er full-suspension bike in existence. It received the MTBR.com award for best 29er and Mountain Bike Action readers picked it as the #1 choice for their next 29er. The combination of Pivot design and dw-link® suspension makes for a bike that accelerates, descends, climbs, and corners unlike any other 29er made- and now it just got better! The All New Mach 429 is both lighter and stiffer as a result of its revised rear triangle design, 1.5” tapered head tube, and a 142 X 12mm rear through axle design with post mount disc brake tabs. Plus, the frame lost over ½ pound in the process, resulting in the Mach 429 not only being the most efficient riding 29er full suspension frame in the world, but also one of the lightest!"
XX build
SRAM XX 2x10 equipped bikes send a clear message as soon as you look at them; "I mean business". The cassettes in themselves are a work of art, while the double chainrings and light weight chain scream loud and clear; "I want to go flat-out everywhere - see you at the top!" The XX clad Mach 429 with DT Swiss 240 wheels is the lightest build you can get and combined with the all-new lighter 429 frame for 2012, you have a serious race-weapon on your hands. You could get it lighter if you really wanted to but Pivot have specced out their flagship build with quality components that are designed to maximise performance out on the trail. Fitting in well with the go fast attitude of the SRAM XX is the Fox Talas RLC FIT fork that has a tapered head tube and 15mm QR for added stiffness, (like Pivot bikes need any more!). If money is no object and your favourite drive train flavour is SRAM, then here is your season pass to off road smiles weekend after weekend.
