TIMEKEEPER

The Timekeeper is our premier road racing tire. Utilizing our signature Rubberforce S tread compound, now mixed with more silica, the Timekeeper is the fastest-rolling tire in the American Classic Road collection. With lightning-fast straight-line speed and confidence-inspiring cornering, the Timekeeper can help you set your next segment PR and climb the ranks of the weeknight crit.

The Timekeeper is available in both Tubeless Ready and tube-type constructions with sidewall color options of black and tan.  The Tubeless Ready version utilizes Stage 3S Armor construction with 120 TPI casing and a 120 TPI skin that when paired with liquid tubeless sealant, provides a more supple and smoother-riding tire. The tube-type version combines 120 TPI fabric with a lighter, more supple, and more puncture resistant Nylon105 belt to provide a faster, more supple, and puncture resistant tube type construction compared to previous American Classic Road tires.

The Tubeless Ready version is designed for both hook-bead (crochet) and hookless rims that follow current E.T.R.T.O. standards. When used with a hookless tire, this tire must never be inflated beyond 73psi or the maximum air pressure rating of the rim, whichever is lower.
