The Chumba EVO:
Form follows function. We've seen the evolution of mountain bike suspension designs, and we've realized its time to bring something new to the market. Using the patent pending Force Channeling Suspension design, we bring you a bike that inspires downhill racing confidence on your descent, while keeping the chassis light.
