American Classic Timekeeper Lightning Fast Tubeless Road Tire 700 X 28

TIMEKEEPER. Timekeeper is our premier racing tire. Featuring our signature Rubberforce S tread compound, now blended with more silica, the Timekeeper is the fastest rolling tire in the American Classic collection. With lightning-fast straight-line speed and confident cornering, Timekeeper will help you set a personal best on the next stage and climb to the top of the weekly race rankings. The Timekeeper is available in both tubeless and tubed construction with sidewall color options of black and brown. The Tubeless Ready version uses Stage 3S Armor construction with a 120 TPI casing and 120 TPI shell, which when combined with liquid tubeless sealant provides a more compliant and smooth ride. The tube-type version combines 120 TPI fabric with a lighter, more flexible and more puncture-resistant Nylon105 breaker to provide a faster, more flexible and puncture-resistant tube-type construction than previous American Classic road tires. The Tubeless Ready version is designed for both hooked rims (crochet), as well as for rims without hooks that comply with current standards ETRTO. When used with a hookless tire, this tire should never be inflated above 73 psi or the maximum rim air pressure rating, whichever is lower.
