Supercaliber 9.8 is a cross country race bike developed for podium-topping World Cup speed. Its category-defining setup features our exclusive IsoStrut integrated shock and a lightweight FOX fork for a capable ride that's flat-out fast and soaks up technical terrain.

It's right for you if...
You want to ride what the pros ride and you want to win. You’re looking for a bike that's built for shocking speed and capability on even the hardest cross country courses, and comes decked out with light, fast upgrades on everything from the fork to the drivetrain.

The tech you get
An ultra-lightweight, full OCLV Mountain Carbon frame with 60mm of travel, a 100mm FOX Performance 32 Step-Cast fork, and Trek's exclusive IsoStrut FOX Performance shock designed specifically for Supercaliber. Plus, dual remote suspension lockout, a SRAM GX Eagle 1x12 drivetrain with carbon cranks, and Bontrager Kovee Pro 30 carbon wheels with 54-tooth Rapid Drive rear hub for fast engagement.

The final word
Supercaliber 9.8 is an efficient and capable cross country race bike trimmed with an upgraded, high-performance parts spec. It's everything you love about a hardtail plus the added capability of IsoStrut—our exclusive integrated shock.

Why you'll love it
- Supercaliber is a World Cup-worthy bike that’s quick, capable of soaring through techy terrain, and nearly as light as a hardtail
- 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
- Wider Kovee Pro 30 wheels provide better tire support so you can run lower pressure and get more traction
