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.
Exceptional Puncture Safety (EPS) offers an added layer of proprietary rubberized poly-fiber material between the tread and the casing. The tight weave of this lightweight, puncture-resistant layer prevents foreign objects from penetrating the casing and damaging the tube.
