The Specialized S-Works Turbo T2/T5 Tire is a tube-type tire optimized for race day and high-speed training rides. The Gripton T2 center compound is fast and efficient in keeping us rolling with speed on the straights, while the T5 compound on the shoulders improves grip for added confidence in the corners. It also features improved puncture protection with the all-new hybrid Kevlar Blackbelt breaker underneath the tread and a light, supple casing.
