Hit the trail.

When your ideal ride plans span everything from fast, XC-style singletrack to gnarly trails, you need a versatile bike that blends snappy and burly to handle it all. The latest Pivot Mach 429 Trail 27.5+ XX1 Eagle Complete Mountain Bike carries the bike's much-loved geometry and 27.5+ compatibility into the new year. Reynolds' plus carbon wheels and SRAM's blingy XX1 Eagle 12-speed drivetrain highlight this build, putting it solidly into dream bike territory.

The 429 Trail's DW-Link suspension owes its capabilities to a handful of queues taken from the Mach 6 and Phoenix, teasing a virtual 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 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 is created using Pivot's hollow-core internal molding process for uniform, controlled wall thicknesses and material distribution. This process virtually eliminates resin pooling and inconsistencies, increasing structural integrity while targeting areas for weight loss. The frame rises from the mold with a 67.5-degree head tube angle 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.

  • A 27.5+ trail bike that balances XC speed and big hit durability
  • 4.5in of responsive DW Link suspension
  • Geometry sits on the slack side of moderate for bigger lines
  • Carbon construction targets low weight and high stiffness
  • Boost axle widths further increase stiffness
  • Wide PF92 bottom bracket complements axles for snappy handling
  • External cable routing lowers cost and allows easy maintenance
  • One-by 12-speed drivetrain provides wide gear range
