Challenge Criterium Tubular Tyre

Challenge Criterium Tubular Tyre

The Challenge Criterium tyre is a modern reincarnation of the once insurpassable Clement Criterium tubular tyre. It is made with the same machines as the Clement, in the same traditional method unlike modern tubulars where many steps are left out for cost cutting and weight measures. 

The outer tread is hand-glued onto the casing while it is under pressure, ensuring that the tyre does not deform when the tyre is pumped to in excess of 110psi for use. This results in a better gripping tread. 

Seamless latex tubes are incorporated into the tyre. Latex is lighter and more supple than normal butyl tubes, meaning that they ride more comfortably and bend/deform around irregular objects on the roads that could otherwise cause a puncture. To further prevent puncture, Challenge has incorporated the PPS (Puncture Protection System), which consists of a belt of corespun polyester (300 tpi polyester) installed between the casing and the tread, giving more protection under the tread.
