The right product can make your cycling dreams come true. American Classic exemplifies the pinnacle of performance in bicycle engineering and innovation. What started as a drive to create better, lighter products has led to industry-leading manufacturing facilities. And our latest developments allow us to provide you with a growing line of performance bicycle tires.

Let us take you on your next adventure. Founder Bill Shook was a talented professional road racer on the US National Team. A drive to create better, lighter products inspired him to start experimenting in his garage, engineering his own aluminum bicycles and components. As demand grew, partnerships began with the finest production facilities in Taiwan. This eventually led to our own factory with control over all aspects of production from prototype to manufacturing.

Kimberlite Fast Rolling Adventure Tire

For fast adventures on both pavement and gravel, look to the Kimberlite tire. This go-anywhere tire performs like a road tire on pavement and hooks up on hardpack dirt surfaces. The semi-slick tread starts with a smooth center for decreased rolling resistance on smoother surfaces, transitions thru progressively more aggressive zones for maximum lateral traction, and wraps up with robust edge knobs for dependable cornering.

The Tubeless 120 TPI casing provides the ultimate construction for speed and comfort, and the Stage 5S Armor provides a tire that is lighter, faster, and more cut, tear, and abrasion resistant.

Features - Tubeless Ready when used with liquid tubeless sealant - Inner Tube compatible - Compatible with traditional hookbead and hookless rims that meet ETRTO standards - Black, Tan, or Brown sidewall - Supple 120 TPI Casing - Gravel specific Rubberforce G tread compounds - Off-road focused Stage 5S Armor construction

Stage 5S Armor Construction Stage 5S Armor is American Classic's gravel specific tire construction combining 120 TPI casing fabrics, Rubberforce G tread compounds, a tubeless ready coating, and a Nylon105 bead-to-bead fabric that provides a tire that is lighter, faster, and more cut, tear, and abrasion resistant than our original Stage 5S Flat Protection.

Rubberforce G Compound Rubberforce G is our family of tread compounds designed for American Classic gravel tires. The high structure and high specific surface area (SSA) of the carbon black provide excellent abrasion resistance, high tensile strength, and good tear and cut resistance for off-road adventures. The final compounds are specific to the intended riding type of the specific tire model.

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.

FAQ 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.

Q. Can this tire be mounted to hookless rims? A. This tire is compatible with hookless rims, also know as TSS in global standards. When mounting on hookless rims, be sure to use compatible rim widths for the specific tire width and never exceed the maximum air pressure for the tire or rim, whichever number is lower.

Q. What is the brown stripe on my brown tire? A. American Classic's brown tires use a 'clear' rubber which allows the overlap of material along the bead to be visible as a darker, angled stripe. This is normal and will not affect ride quality or longevity.
