2017 Pivot Mach 429 Trail 27.5+ XT/XTR Pro Complete Mountain Bike


The much-loved Pivot Mach 429 Trail is back for the 2017 model year relatively unchanged save for the expansion to include a 27.5+ wheel size option for an added dose of versatility. The 2017 Pivot Mach 429 Trail 27.5+ XT/XTR Pro Complete Mountain pairs the aggressiveness of a nimble XC rig with beefy axle widths and plus-sized tires for a stiff, responsive ride. Kitted out with a mix of Shimano’s XT and XTR componentry, 130mm of plush Fox Racing Shox front travel, and a fast rolling set of DT Swiss XM 551 hoops, this whip is ready to shred.

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 more width across the board: hubs, chainstays, bottom bracket, and chassis. This makes for a shallower spoke angle, which considerably stiffens the 429 Trail’s wagon wheels. It also accommodates wider pivot placement for longer life in the suspension bearings and a stiffer rear triangle. That extra width leaves room to slam the rear wheel up, too, shortening the chainstays for even more efficiency and dexterity, and allows compatibility with 27.5+ tires. The externally routed cables make for easy maintenance, which we like, and also lower the bar for entry by reducing the manufacturing cost, which we like even more.
