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.

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!
