Trek Procaliber 9.9 SL

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
