When it comes to cross country hardtails, it doesn't get better than Procaliber 9.9 SL. The highest-end mountain bike in Trek's Procaliber family is dressed to impress, with an SL OCLV Mountain Carbon layup that's a lot lighter than our non-SL frame, an advanced RockShox SID SE Carbon fork, Bontrager Kovee Pro 30 carbon wheels, and a SRAM XX1 Eagle drivetrain.

It's right for you if...

You're riding every day, racing every weekend, and want an no-compromise XC bike that goes as fast as your heart, legs, and lungs can carry you. You want a rig with a top-level spec that adds speed and efficiency without adding weight, and you know an investment in a great race bike has a return in results.

The tech you get

A race-ready XC bike under 19.5 pounds. Trek's superlight SL OCLV Mountain Carbon frame with trail-smoothing IsoSpeed, RockShox SID SE Carbon fork with remote lockout, Bontrager Kovee Pro 30 carbon wheels with a 108-tooth Rapid Drive rear hub for instant engagement, SRAM XX1 Eagle 1x12 drivetrain, superlight SRAM Level Ultimate carbon hydraulic disc brakes, and Bontrager XXX carbon seatpost and handlebar.

The final word

Smoother. Lighter. Faster. This bike was built to win the XC game. Its ultra-lightweight frame and top-of-the-line spec was made to go fast, with serious performance fit for a serious rider.

Why you'll love it

1 - There's nothing left to want on this bike - in no uncertain terms, it has the best of everything
2 - It's crazy light, super fast, and efficient - all qualities that really matter when you're gunning for the podium
3 - The IsoSpeed decoupler makes it ride smoother than any other hardtail, so your body doesn't get beat up by trail chatter
4 - Carbon parts all over will turn heads at the start line and podium - the only two places your competition is likely to see you if you're riding this bike to its potential
5 - Make it yours: customize your ride through Project One
