In creating the 2016 Mach 429 Trail X1 Complete Mountain Bike, Pivot took a bit of a mad scientist approach, piecing together a bike that tackles big hits with lithe, nimble style. With inspiration from the sprightly cross country 429SL, enduro beast Mach 6, and downhill demon Phoenix paired with Fox's trail suspension kit and a dose of SRAM X1 componentry, the Mach 429 Trail manages to simultaneously haunt the worlds of XC and enduro, hitting all the marks for a quiver killing trail bike. The 429 Trail's DW Link suspension owes its versatile capabilities to a handful of queues taken from the Mach 6 and Phoenix, teasing a depth out of the 116mm 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. The frame itself begins life with Pivot's 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 tumbles out of the mold with 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. Pivot teamed with Shimano to design a bottom bracket shell that meshes seamlessly with the Japanese firm's PF92 standard. The wide bottom bracket anchors the unbelievably stiff Boost 148110 axles...
