Experience matters. Our new X-Caliber 29 hardtail mountain bikes benefit from over 15 years of 29er R&D. They're the lightest, fastest, smartest 29" hardtails on the market.

Upgrades from X-Caliber 4

  • RST Blaze 100mm fork
  • Bontrager AT-650 double-walled rims
  • Shimano M171 crank
  • Shimano Acera rear derailleur
  • Tektro HDC 300 hydraulic disc brakes

G2 Geometry

Advanced frame geometry and a custom offset fork give our 29ers precise handling at low speed without compromising high-speed stability.

Alpha Gold Aluminium

Trek’s high-performance aluminium, with manipulated tube shapes to balance strength and weight saving.

29" wheels

The gold standard for smooth, stable riding. Bigger wheels carry more momentum, roll over obstacles more easily, and offer greater stability and more traction than smaller options.

Extended size range

A wider range of sizes than the industry standard provides more options for everyone, from tallest to shortest and all those in between. Because everyone deserves a great ride.
