Trek X-Caliber 9 Mountain Bike 2023

Trek’s X-Caliber 9 Mountain Bike is a cross country race-ready steed with an efficient, lightweight Alpha Platinum Aluminium chassis, featuring internal cable routing. The RockShox Recon Gold fork adds 100mm of suspension for comfort and control. The travel can be locked out for maximum efficiency when climbing steep hills and opened up again to soak up the rough stuff.

The frame also features an internally routed dropper seatpost that lets you lower your saddle, so it’s out of the way for tricky sections. The 1x Shimano groupset consists of an SLX shifter and wide-ranging 10-51 cassette with an XT rear derailleur to ensure smooth and accurate shifting. The hydraulic disc brakes provide powerful, reliable all-weather performance. Frame size-specific wheels, with the smaller sizes getting 27.5” and the larger sizes 29”, ensure effective control and responsiveness across all sizes.

Highlights

  • High-end XC parts on an incredible frame perfect for cross country racing
  • The clutch rear derailleur prevents chain slap, even in the rough
  • The 1x drivetrain delivers a wide range of gearing with the simplicity of a single shifter
  • Tubeless-ready wheels with wider Boost141 hubs for increased wheel strength and better tyre clearance
  • The front suspension feature a lockout for increased pedalling efficiency
  • Smart wheel sizing pairs the perfect wheel combination with frame size for better control
