Trek (United States) - Press Release: The smarter hardtail.

Procaliber sets the bar for hardtail speed and smarts. It's the fast, ultra-light cross country ride that rules the singletrack; from the local race scene to the World Cup XC.

Procaliber's innovative IsoSpeed decoupler delivers uncompromising XC performance, efficiency and an incredible ride feel. It's the fastest, smoothest, smartest hardtail on the trail.

IsoSpeed decoupler:

Smooth means fast. Our innovative decoupler increases vertical compliance without sacrificing efficiency. You ride faster, longer and stronger.

Doubly stiff: Boost148/110:

The wider 148mm rear and 110mm front hub spacing on 29ers creates stronger, less flexy wheels and allows for wider tyres, shorter chainstays and more chainring options.

Light, lighter or lightest:

Choose Alpha Platinum Aluminium, OCLV Mountain Carbon or the featherweight SL for World Cup-calibre performance.

Smart Wheel Size:

One wheel size does not fit all. We put the right size wheel on every frame: 27.5˝ on 13.5˝ and 15.5˝ frames, 29er on 17.5˝ and up. Everyone wins.

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 our Procaliber family is dressed to impress, with an SL OCLV Mountain Carbon lay-up 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.
