Challenge SuperLite Cross Latex CX Inner TubeLatex inner tubes: Used in all high end tubular thanks to their low rolling resistance. Thinner and more flexible than butyl tubes.The use in open tubulars increases comfort and lowers rolling resistance. Latex is also more resistant to punctures. On the other hand it is a porous material therefore it requires daily inflation. Saving more than three watts per wheel over a butyl inner tube, this road bike tube gives you lighter and softer performance.Puncture protection is also greatly improved as latex extends and expands 7 to 8 times its original size, whereas butyl only about 1.5x meaning that latex is much, much more flexible and not immediately prone to punctures. Unlike the stiffer butyl, latex will first expand and wrap itself all around a protruding object and often isn't successful puncturing through even after working itself all the way in the tyre.The best performance and comfort combination is the latex inner tube with a handmade clincher, although the latex tube can also improve the ride of any other type of clincher.Replacing the standard butyl inner tubes (even superlight ones) with the Challenge seamless latex inner tube is by far the most affordable way of improving the performance and overall feel of your bike.Features: Use: Handmade Clincher Tyres Valve: Presta Removable Core Valve Length: 48mm Size: 700 Tyre Width: 29-38mm Weight: 75gBuy Challenge Wheels & Tyres from Chain Reaction Cycles, the World's Largest Online Bike Store.
Challenge Baby Limus Open Cyclocross TyreWith Limus outer knobs for good traction in the bends and lower faster centre line knobs (for more all-around use), it's also wide spaced for dirt/mud clearance. The Baby Limus is the perfect tyre for winners.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. This all-round cyclocross tyre is a perfect choice of upgrade for staying in control as you ride across wet sand or sticky mud terrain 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: 360gTechnologies: 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 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.

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.
