More Information
In 1990, Max Brauns was driven by a passion for hand-crafted performance tyres and moved to Thailand, where the World's best natural rubber (rather than artificially-produced petroleum-based rubber) could be sourced. In 2000, Challengetech was born.
Challenge Criterium SC S 25 700c Tubular Road Tyre

The Criterium SC S 25 is a handmade tubular tyre with the Challenge Corespun Cotton casing and a PPS layer. Designed for road racing, this tubular tyre features the Challenge SuperPoly polyester casing for durability. The natural rubber used to make the tread provides superior grip. A layer of uniquely-crafted fabric with highly resistant properties sits between the casing and the tire to reduce the risk of punctures.
