Those hills aren't looking any smaller and the guy behind you just keeps getting closer. When every gram counts on race day, wrap your race hoops in the 4ZA Cirrus Pro road tire. It's an ultra lightweight clincher tire that's designed to eliminate all spare weight and wasted energy from your bike to get you to the finish line before the other guy. The single compound construction provides the lowest possible rolling resistance and fantastic cornering grip, while the fast rolling slick tread gives no energy up to the road.
