Challenge Almanzo Gravel Open Tubular TyreThis 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.Features: Use: Hard Pack Dirt to Light Gravel Size: 700 Tyre Width: 33mm Internal Rim Width: 15-19mm TPI: 260 Bead: Aramid Casing: SuperPoly Flat Protection: Double PPS BAR: 3-9 PSI: 45-130 Weight: 385gTechnologies: 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.Buy Challenge Wheels & Tyres from Chain Reaction Cycles, the World's Largest Online Bike Store.

While this is an old technology for cars and trucks, for bicycles it is relatively new and did not even have an internationally accepted design standard (ISO or ETRTO) until recent years. By eliminating the inner tube it is possible to lower the weight and create a softer, more comfortable, more efficient, lower rolling resistance tyre system by running lower tyre pressure. Challenge started introducing Vulcanized Tubeless Ready (VTR) tyres in recent years because the ISO and ETRTO standards for proper VTR tire and rim fit have finally been completed. These standards ensure your safety and your ability to fit and service the tyres with hand tools. Buy Challenge Wheels & Tyres from Chain Reaction Cycles, the World's Largest Online Bike Store.
