B-Fast C1870

Hard PackLoose Over HardMedium

The B-Fast XC mountain bike tire from CST is driven by performance.

 

The design was built for one thing- speed. The tightly packed center knobs eliminate rolling resistance so you can widen the lead, while widely spaced shoulder knobs bite in on technical sections. The B-Fast is available in wire and folding bead with EPS protection.
