Supercaliber 9.9 is the fastest, lightest, and most capable cross country race bike we make—and that's exactly why it's Trek Factory Racing's World Cup bike of choice. The exclusive IsoStrut top tube shock is the cornerstone of Supercaliber's efficient suspension system, giving you a fast and light ride that charges through rugged terrain at breakneck speed.

It's right for you if...
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—plus tons of carbon—for knock-out, drag-out speed and capability.

The tech you get
An ultra-lightweight, full OCLV Mountain Carbon frame with 60mm of travel, a 100mm FOX Factory 32 Step-Cast fork with FIT4 damper, and Trek's exclusive IsoStrut FOX Factory shock designed specifically for Supercaliber. Plus, a full SRAM XX1 Eagle 1x12 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.

The final word
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. Saddle up and see what you're made of.

Why you'll love it
- Supercaliber 9.9 is the ultimate XC race bike, one you'll see taking top spots during the World Cup
- Our exclusive IsoStrut shock provides tuneable, damped suspension for a smooth and efficient ride
- 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
