Just in time to satisfy a ravenous and ever growing 429 fan base, we present the Pivot Mach 429SL Carbon X01 Reynolds Bike. Combining a lighter chassis and an uncompromising SRAM X01 build with Reynolds Carbon Wheels, it's a package that's assertively top tier and future proof.The Pivot Mach 429SL Carbon drops a half pound from its predecessor, the Mach 429 Carbon. To a manwoman, the original 429 Carbon was lauded by our crew for its combination of climbing ability and descending prowess, and for its eagerness to be driven hard. On the trail, it was the stiffest bike we could find in the short travel 29er crowd. The few dissenting opinions regarding that bike came from Lycra wearing types compelled to cut grams at all costs, who cited the 429 Carbon's weight as a limiting factor. Now there's little left to argue about. With the 429SL, weight weenies no longer have an excuse to pass the incomparable 429 by. Pivot achieved a half pound lighter weight for the 429SL via its use of proprietary hollow core, internal mandrel technology, the same process that was employed for the 429 Carbon. Pivot scrutinized its 429 layup, refining both the structure and the composite materials used. As a result of those efforts, the podium hungry Mach 429SL Carbon is one of the lightest full suspension bikes Pivot has ever made 5. 3lbs, min. But if you think Chris Cocalis and co. would sacrifice ride quality for a number on the scale, think again. To Pivot, stiffness comes first. Expectedly, the 429SL tracks over rough terrain with unwavering accuracy. Hard corners, off camber landings if you feel some flex from the Mach 429SL, it's almost guaranteed to be coming from the wheelstires, and that gives you ample control to ride at the edge of sanity.Suspension duties for the Mach 429SL are handled by the proven DW link design, which yields 100mm of smooth travel while counteracting speed robbing pedaling forces. This translates to race worthy acceleration and consistent contact w...
