Open Tubular (Clincher) An open tubular is constructed using the same casing and tread materials and process as a tubular, but instead of sewing the casing together (closed), the sides of the tubular casing are folded around aramid fibre cords to produce beads. This ‘open’ design performs like a tubular, yet conveniently mounts like a standard clincher tyre. If combined with a Latex inner tube the ride becomes even closer to that of a tubular, offering excellent traction and cornering, low rolling resistance and shock absorption.

Challenge Grifo Open Pro Cyclocross Bike TyreDeveloped for the rigours of modern cyclocross (CX) racing, this race-ready tyre provides exceptional grip and low rolling resistance as you tackle the more demanding of terrain and course conditions. Featuring a handmade construction, this clincher model's casing is produced with technical materials like Corespun (a cotton and polyester combination). Corespun is a thread from which Challenge obtain a very supple and strong casing with low weights. The casings have a high TPI count that can reach over 300 tpi and production avoids any vulcanisation process to enable all materials to keep their suppleness and flexibility. Handmade Cyclocross Clincher TyreThe tread is slowly hand glued on the casing which is previously mounted and inflated on a rim. By using this method, the tread is relaxed on the casing and does not suffer any tension when inflated. The result of this is a lower rolling resistance, increase in comfort, more precise handling of the bike and better grip.Increased Comfort, Flexibility and Puncture ResistanceTo give the best possible grip in curves Challenge uses materials to obtain flexibility and suppleness, which results in absorption of irregular surfaces giving to the cyclist the best possible contact patch. The wheel avoids jumping and the tyre will deform and absorb the irregularities acting in some way as a shock absorber. A special fabric is placed between the tread and casing to increase puncture resistance PPS (Puncture Protection System) technology. Classed as one of the best all-around cyclocross tyres ever created by the brand, the Challenge Grifo Open Pro Cyclocross Bike Tyre excels in wet, dry, soft packed, rocky and root-infested course conditions.Features: Use: Cyclocross Racing: All Around Soft Pack Tyre Type: Clincher Size: 700c Type Width: 33mm Internal Rim Width: 15-19mm TPI: 300 Bead: Aramid Casing: SuperPoly Flat Protection: PPS Recommended Pressure: BAR: 2.1-2.7; PSI: 30-40 Tubeless Ready: No Single or Pair: Single Weight: 355gTechnologies: Challenge Handmade Clinchers (HCL): This handmade clincher is made from the same materials and processes as the brand's handmade tubulars but instead of sewing an inner tube inside the casing is wrapped around a aramid bead to form a tyre 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.Buy Challenge Wheels & Tyres from Chain Reaction Cycles, the World's Largest Online Bike Store.
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.

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.
