Optimised for early season cyclocross races. Micro-diamond knobs adorn the tread surface to offer blazing speed on hardpacked surfaces, while stacked paddle knobs down the middle offer unrivalled climbing and braking traction. When the course gets twisty, the siped and offset cornering knobs will dig in to give you the support to brake later and push your tires as hard as your legs.Key Features:File tread design optimized for grass and hardpack,Aggressive cornering knobs,EXO Protection,Tubeless Ready (TR).Specifications:Conditions: Hardpack, Loose/Hard,Cornering Control: 1 2 3 4,Rolling Efficiency: 1 2 3 4,Compound: Dual compound technology,Breaker: EXO Puncture protection,Tubeless Tyre,Max PSI: 75,Bead Type: Folding,TPI: 60,Weight: 395g.Tubeless Ready: Tubeless tyres provide the rider with many benefits: the ability to run lower air pressures, which improves traction; lower rolling resistance when compared to a tube-type tyre; and less chance of flatting since there is no tube. Maxxis Tubeless Ready (TR) tyres provide the benefits of a UST tubeless tyre without the weight penalty. Our TR tyres use a standard casing and require the use of a liquid sealant in order to make them airtight. Maxxis Tubeless Ready tyres are the only Maxxis tyres approved for use with liquid sealants.EXO: An extremely cut-resistant and abrasion-resistant material added to the sidewalls of select mountain tyres. This densely woven fabric is also lightweight and highly flexible, ensuring that the performance of the tyre remains unaffected. Choose EXO Protection for exceptionally rocky, treacherous trails where the chance of sidewall cuts and abrasions is high.
A gravel tyre for riders willing to brave aggressive terrain with only their drop bars and a tiny amount of rubber beneath them. Raised square-edged centre knobs provide climbing and braking traction on dust-covered trails, and oversized cornering knobs keep you and your gear out of the dirt to conquer another turn.Aggressive gravel tire,Optimal for off-road touring and adventures,Tubeless Ready (TR),.SpecificationConditions: Looser Over Hard, Medium, Loose,Cornering Control: 1 2 3 4,Rolling Efficiency: 1 2 3 4,TPI: 60,Bead: Foldable,Ply Construction: Dual,Compound: Dual,Max PSI: 75,Tech: Tubeless Ready, SilkShield,.TechnologyTubeless Ready: Tubeless tyres provide the rider with many benefits: the ability to run lower air pressures, which improves traction; lower rolling resistance when compared to a tube-type tyre; and less chance of flatting since there is no tube.

Challenge Grifo Team Edition Cyclocross 700x33c Tubular Working in conjunction with elite athletes, Challenge has developed the best all-around cross tubular ever, one that excels in wet or dry, soft packed, rocky and root-infested courses. The Grifo team edition tubular features fast-rolling knobs and a centre section that offers excellent pedalling and braking traction. The casing is produced with the latest technical materials like Corespun (a cotton/polyester mix). Corespun produces a tyre casing that is very supple, strong, and low in weight. The tyres high TPI count (threads per inch) in conjunction with a latex inner tube adds flexibility, allowing it to conform better to the terrain, improving impact and vibration absorption while reducing rolling resistance for ultimate speed. Puncture protection comes in the form of a a specially designed fabric that is placed between the tread and casing. This PPS (puncture protection strip is resistant to foreign object penetration and cuts.

This tyre is also designed to be super-fast rolling with maximum control on dry hard pack, wet grass or even icy riding conditions Technologies: 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 tyre 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 tyre 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 tyre’s stiff sidewall compromises its ability to equal a supple HCL with a latex inner tube.
Challenge Chicane Open Cyclocross TyreDrill the straightaways with confidence knowing the Chicane will carry you through sand, dust, snow or whatever the approaching corners throw at you. The ultimate fast tyre with superior cornering traction.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.
