    • Challenge Almanzo Gravel Open Tubular Tyre

  • Challenge Almanzo Gravel Open Tubular Tyre

    This highly-effective gravel tyre features a tubular construction and double-layered puncture protection for excellent durability. The ‘open’ design of the tyre performs like a tubular, yet conveniently mounts like a standard clincher tyre. Plus, its tight tread offers excellent grip at high speeds, making it a reliable racing tyre even on tougher surfaces. Designed to give you more control than the Strada Bianca tyre and faster rolling resistance than the Gravel Grinder when cornering.

    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.
