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 6

  • SR Suntour XCR fork
  • Shimano Acera 9-speed drivetrain
  • Shimano Acera M391 crank

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 Aluminum

Trek’s high-performance aluminum, 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.

Suspension lockout

Lock out the suspension fork for efficient riding on smooth terrain.

Extended size range

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

Internal derailleur routing

Route your derailleur cables through the frame to keep your bike running smooth and clean.
