Hand Assembled Challenge 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 Absorbing The 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. Technologies: 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.
Giving you fast rolling and cornering, this world-class tyre is a perfect upgrade for riders who want maximum control in all riding conditions. Technologies: Challenge Handmade Clinchers (HCL): This Handmade Clincher is made from the same materials and processes as 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.

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.
