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.

Perfect for all riding conditions, this tyre gives you fast-rolling resistance and excellent handling when cornering. 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 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.

Challenge Strada Bianca ProTubular Cyclocross TyreThe Challenge Challenge Strada Bianca ProTubular Cyclocross Tyre offers world-class fast rolling resistance and is specifically designed for gravel riding and racing. It's also ideal for those with gravel bikes who are looking for a tyre that enables you to run lower pressures for more comfortable road riding without the worry of puncturing. This is thanks to the double PPS (Puncture Protection System) between the tread and casing, which provides excellent durability without excess bulk.Hand AssembledChallenge uses the latest technical materials such as corespun for the inner casing of these tyres. This material produces a very high TPI (threads-per-inch) count to ensure the ultimate in strength, suppleness, and low weight. This casing is then hand glued on to the tread, which has previously been installed and inflated on a rim. This means that when the assembled tyre is inflated, it provides more precise handling, lower rolling resistance, and better grip.Shock AbsorbingThe best materials have been used to obtain consistent grip over uneven terrain and reduce the vibration feedback to the rider, helping you to maintain grip and control on even the longest and roughest races. The advanced design reduces wheel skipping and jumping over rough surfaces, ensuring efficient grip and helping you to maintain your speed. These tyres also feature a double layer of Challenge's PPS (puncture protection system) between the tread and casing, to give you confidence when blasting over tree roots and sharp rocks.Features: Size: 700 Tyre Width: 30mm Internal Rim Width: 15-19mm TPI: 260 Casing: SuperPoly Flat Protection: Double PPS BAR: 4-10 PSI: 60-150 Inner Tube: LatexTechnologies: Challenge Handmade Tubulars (HTU): Our Handmade Tubular (HTU) tires perform better than any tubeless system! Therefore, they are raced by all the top athletes and teams in every cycling segment. The latex inner tube we cradled inside the high-quality casing that is sewn shut, forming a soft protective layer for the delicate tube. A base tape is glued over the sewing for protection and to absorb the adhesive later applied to hold the tubular on the rim. The carcass is mounted on a rim, inflated and a special natural rubber tread is precisely glued on top. Puncture protection layers and sealants can be applied to the finished casing, depending on the tubular's use.Buy Challenge Wheels & Tyres from Chain Reaction Cycles, the World's Largest Online Bike Store.
