Timekeeper

Lightning-Fast Road Tire

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 Stage 3S Armor construction utilizes 120 TPI casing and a 120 TPI skin that when paired with liquid tubeless sealant, provides a more supple and smoother-riding tire.

Stage 3S Armor Construction The Stage 3S Armor construction is American Classics lightest construction for tubeless ready road tires adding both lightweight 120 TPI casing with an additional 120 TPI skin fabric, and, when combined with tubeless sealants, creates the ideal puncture protection and low rolling resistance.	Rubberforce S Compound Rubberforce S is our family of tread compounds designed for American Classic road tires. Each road tire model receives a specially formulated mixture of compounds to provide the optimal grip, strength, and speed for the intended use. This tire includes a mixture of silica for added durability, grip, and maximum speed for road racing.	Precision Engineering Since 1982, American Classic has been leveraging our expertise with unique manufacturing systems and emerging technologies to provide premium quality products for your bicycle.

Q. Why does my tire size not match the listed size?

A. Tire size is dependent on the width of your rim. Use on a narrow rim will cause the tire to be narrower than listed. And mounting on a wider rim will cause the tire to measure wider. Rim sizes are listed in the chart below.

Q. How does Tubeless Ready differ from Tubeless?

A. Tubeless Ready ready tires are lighter weight, and more supple, than traditional tubeless tires. Tubeless Ready tires require the use of tubeless sealants to properly seal and retain air pressure.

Q. Will these tires be difficult to install?

A. American Classic tires follow the latest global industry standard for size and fitment and are intended to be mounted on rims that follow those same standards. Up until around the year 2000 a few popular US wheel brands were making rims that were oversized. Mounting our standards based tires on those oversizes rims will require greater effort than mounting to industry standard rims.
