Challenge Strada Open Road TyreThe famous all-round use, good rolling tread design in a supple, comfortable 25mm size, also now available in ‘Open Tubular’ clincher. Designed for all roads, this tyre gives you world-class fast rolling and cornering as well as maximum control as you clock up the miles.Features: Use: Road Racing, Big Rider, Rough RoadsSize: 700Tyre Width: 25mmInternal Rim Width: 13-17mmTPI: 300Bead: AramidCasing: SuperPolyFlat Protection: PPSBAR: 7-10PSI: 100-145Weight: 240gTechnologies: 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 Limus Open Cyclocross TyreDeeper 33mm knobs for increased traction in deep mud. Speed and max. traction all in one.Open tubular differ from traditional clinchers for the construction. The Tyre is produced just like a tubular and uses the same materials and production process. 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.Features: Use: Cross Racing: All around, Sticky Mud Size: 700 Tyre Width: 33mm Internal Rim Width: 15-19mm TPI: 300 Bead: Aramid Casing: SuperPoly Flat protection: PPS BAR: 2-6 PSI: 30-90 Weight: 370gTechnologies: 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.

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.

This tyre features a central ramped tread profile for easily acceleration, as well as aggressive side knobs for superb grip on corners and technical trail sections. This tyre is engineered to be robust, reliable and dependable - the Grifo is a very worthy addition to your racing/training arsenal. Classed as one of the best all-around cyclocross tyres every created by Challenge, this tyre excels in wet, dry, soft packed, rocky and root-infested course conditions Technologies: Vulcanized Tubeless Ready (VTR): The highest level of performance offered by car, truck and motorcycle tyre manufacturers is a vulcanized tubeless system. 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.
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.
This tyre features a bold 120 tpi Nylon casing, vulcanised for added protection. Plus, it stands up brilliantly to the rough and tumble of such riding for a confidence-inspiring performance on every outing. Giving you fast rolling and cornering, this world-class tyre is a perfect upgrade for riders who want maximum control in all riding conditions.
