Challenge Grifo Team Edition Cyclocross 700x33c Tubular Working in conjunction with elite athletes, Challenge has developed the best all-around cross tubular ever, one that excels in wet or dry, soft packed, rocky and root-infested courses. The Grifo team edition tubular features fast-rolling knobs and a centre section that offers excellent pedalling and braking traction. The casing is produced with the latest technical materials like Corespun (a cotton/polyester mix). Corespun produces a tyre casing that is very supple, strong, and low in weight. The tyres high TPI count (threads per inch) in conjunction with a latex inner tube adds flexibility, allowing it to conform better to the terrain, improving impact and vibration absorption while reducing rolling resistance for ultimate speed. Puncture protection comes in the form of a a specially designed fabric that is placed between the tread and casing. This PPS (puncture protection strip is resistant to foreign object penetration and cuts.

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.

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. Built for the intensity of riding in extreme conditions, this tyre is a perfect upgrade for maximising your control during muddy conditions. Technologies: Challenge Handmade Clinchers (HCL): These 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 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. 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.
