Challenge handmade tires combine comfort, performance, and grip in a way other tires can't match. Our handmade tires are assembled step-by-step by experienced craftspeople. High quality natural glues and latex coatings are applied to ultra-supple casing materials like silk, cotton, or polyester. The result is a small-batch tire with a ride feel that is simply on a different level.

Race Day Performance – The go-to for our professional athletes, TEAM EDITION tires are a step up in casings and compounds and are the ideal balance of features for special efforts.

Corespun Cotton with thread counts of 320-350tpi is naturally softer and more supple than polyester but is more likely to absorb water so we seal our cotton sidewalls for increased durability.

A more compliant rubber compound fine-tuned by Cyclocross World Champions for a smooth ride and maximum grip. SMARTsoft is also used on the special tires we developed with British Cycling for their Track program.

Our Puncture Protection System (PPS) is a tough, tightly-woven fabric placed between the tread and casing to increase puncture resistance.
