What is IsoBow technology?

IsoBow is Trek’s carbon frame compliance system that reduces trail vibration without affecting stiffness. It helps smooth out rough terrain and improves comfort on long XC rides.

Should I choose aluminium or carbon?

Aluminium models offer durability and value, while OCLV Mountain Carbon frames provide lower weight, improved compliance and a more responsive ride feel.

Is the Trek Procaliber suitable for racing?

Absolutely. The Procaliber is raced at XC events worldwide and is designed for riders who want maximum efficiency, fast acceleration and precise handling.

Can the Procaliber handle rough trails?

Yes, within reason. It is a hardtail built for XC terrain, so it excels on singletrack, roots, rocks and rolling trails, but it is not intended for enduro or aggressive downhill riding.

What wheel and tyre sizes does it use?

All models run 29in wheels with clearance for up to 2.4in tyres, giving a balance of speed, grip and rolling efficiency.
