Trek Procaliber 9.7 Viper Red 2017
In mountain biking's heyday, Procaliber was the envy of all other race bikes. Now it's back to rule the XC circuit once again, redefining the term “hardtail” and setting the bar for speed and smarts.
Procaliber's IsoSpeed decoupler delivers uncompromising cross country performance, efficiency, and an incredible ride feel. It's the fastest, smoothest, smartest hardtail on the trail.
