Specialized Cotton Racing 700c Tire Race-Day Feel, Everyday Ride Ready Cotton casing is what separates a race tire from other tires. The Cotton Racing Tire puts a 320 TPI poly-cotton casing under you, and that thread count translates directly to compliance, low rolling resistance, and a ride quality that synthetic casings at this price simply can't match. The GRIPTON T2/T5 dual compound keeps rolling efficiency high through the center and dials in cornering grip at the shoulders. This is a tubed clincher built for riders who know what they're putting on there bike on race day and want that same feel every time they go out.
