Supercaliber 9.9 XX1 AXS

You're gunning for the top spot and looking for a pro-level cross country race bike that has top-of-the-line everything. You want a bike that comes spec’d with the best parts and suspension available—including a fully wireless electronic drivetrain—for knock-out, drag-out speed and capability.

An ultra-lightweight, full OCLV Mountain Carbon frame with 60mm of travel, a 100mm RockShox SID Ultimate fork, and Trek's exclusive IsoStrut FOX Factory shock designed specifically for Supercaliber. Plus, a fully wireless SRAM XX1 Eagle AXS 1x12 electronic drivetrain, Bontrager carbon wheels with a 54-tooth DT Swiss rear hub for fast engagement, SRAM Level Ultimate brakes with carbon levers, and a Bontrager XXX carbon seatpost and handlebar.

If you don’t podium, sorry, but you can’t blame it on this bike. Its insanely light carbon frame is spec'd for the pros using the most advanced MTB components out there, including our cutting-edge IsoStrut integrated shock and a fully wireless SRAM XX1 Eagle AXS drivetrain.

The SRAM XX1 Eagle AXS drivetrain is smart, smooth, and completely wireless
Our exclusive IsoStrut shock provides tuneable, damped suspension for a smooth and efficient ride without the weight of full suspension
Pivotless seat stays save on weight and actively bend to help soak up trail chatter
TwistLoc simultaneously locks out front and rear shocks for climbs and sprints with the simple Grip Shift-like motion
Wider Kovee XXX 30 wheels provide better tire support so you can run lower pressure and get more traction
