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.
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.
The Challenge Almanzo is perfect for adventure and gravel riders who want more control than the Strada Bianca, but with lower rolling resistance and weight than the Gravel Grinder.File tread pattern with exaggerated side tread for excellent speed and grip260TPI SuperPoly & CorrazzaArmor casing gives an incredibly smooth and supple rideHandmade folding bead casing with PPS Ganzo and PPS2 puncture protectionSmartPlus rubber compound for excellent grip and durabilityNot tubeless compatibleThe Almanzo's file centre tread gives it incredibly low rolling resistance, so it speeds a long easier than the Gravel Grinder without giving too much away to the much slicker Strada Bianca. Compared to the Strada Bianca though, the Almanzo's exaggerated side tread gives bundles of confidence in loose corners, so you can attack them.On rough gravel trails, you need confidence that your tyres are tough enough for the job and the Almanzo won't let you down thanks to it's double PPS Ganzo and PPS2 puncture protection, while the handmade SuperPoly casing gives it that elegantly supple ride that marks Challenge's handmade tyres out from the rest. If you want a highly versatile, lightweight and tough tyre for your gravel bike, the Challenge Almanzo is up to the task.
