    • Challenge Criterium Open Road Tyre

  • Challenge Criterium Open Road Tyre

    Forever the choice of professional riders. Numerous victories and podiums have proven Criterium the top Pro racing tyre.

    Open tubular differ from traditional clinchers for the construction. The Tyre is produced just like a tubular and uses the same materials and production process. Instead of being sewed with an inner tube inside, at the end of the process beads are made by folding the casing around Aramid fibers threads. For this reason an open tubular gives very similar ride feel of that of a tubular, mainly if a latex inner tube is used.

    Mounting an open tubular on a wheel is the same as mounting a standard clincher but with the advantage of riding a much more comfortable and performing tyre. This road tyre is a perfect choice of upgrade for riders who want world-class, super-fast rolling and cornering on every journey.

    Technologies:

    • Challenge Handmade Clinchers (HCL): Our Handmade Clinchers are made from the same materials and processes as our handmade tubulars but instead of sewing an inner tube inside the casing is wrapped around an aramid bead to form a tire that fits on a clincher rim. The HCL is moulded flat, not in a horseshoe like a TLR or VCL. This shape allows the casing to naturally deform over surface imperfections and minimize rolling resistance. A tubeless tire is moulded in a U-shape to make the sidewalls rigid, so the system does not “burp” or lose air when it deforms after it encounters a surface imperfection. The tubeless tire’s stiff sidewall compromises its ability to equal a supple HCL with a latex inner tube.
