The Pivot Mach 429 Trail XT Pro Complete Mountain Bike combines the aggressive angle of attack that made 29ers the kings of XC with stiffness enhancing Boost hubs that eliminate the noodliness and unwieldy chainstays we used to accept as the trade off. Shimano's XT kit recently got a similarly impressive update, inheriting much of the tech of its more expensive stablemate, XTR, but retaining the trail proof reliability and self sponsored pricing that has made it so well loved. Of course, no amount of innovation and drivetrain shininess can make up for a poorly built frame, which is why Pivot developed its hollow core internal molding process for uniform, controlled wall thicknesses and material distribution. This process virtually eliminates inconsistencies and resin pooling, increasing structural integrity while targeting areas for weight loss. The frame has a 67. 5 degree head tube and relatively stubby chainstays, making it slack enough to challenge lines across rock gardens but nimble enough to pick its way through enduro grade terrain all while sticking climbs and roosting berms in the manner that made us fall in love with its immediate predecessor, the 429SL. The 429 Trail's DW Link suspension takes a handful of queues from Pivot's Mach 6 and Phoenix frames, teasing a depth out of the 116mm of travel that feels closer to a proper five inch trail bike. The canny cyclist may spot elements of Pivot's DH clevis and enduro lower linkage in this model, but the completely new upper linkage translates those big hit designs to the traction focused language of a trail bike. By bringing the 429SL's small bump compliance and race worthy trail contact into conversation with the Mach 6's terrain erasing capabilities, the 429 Trail defines the crossroads where XC speed meets fearless, enduro aggression especially when paired with the responsiveness and decreased deflection of the wider, Boost hub standard. The Boost 148 rear and 110 front axle standards allow for m...
