Challenge tubs top casings are made of Silk or top quality cotton weave called Corespun, the next level down being Super Poly. Corespun weave allows them to obtain both supple and strong, but lighter casings at the same time. These very top level casings can reach a TPI (thread per inch) count of over 320TPI. At the next Super Poly level the TPI count can easily reach over 300TPI achieving also very strong and in fact less delicate casings than the higher cotton level.
The casings, which are sewn round with an inner tube inside, are mounted on rims and then inflated and the treads are then slowly hand glued on them. The tread is laid on the inflated casing enabling it not to suffer any tension, instead of being placed on casings which are subsequently inflated. The treads made of all natural (non-petroleum based) rubber, combined (via Handmade production) with the quality, high TPI count casings result in tyres with lower rolling resistance and increased comfort offering a safer and more precise handling of the bike. The tyre absorbs irregularities of the surface with its subtle give and slight deformation, increasing road surface contact and guaranteeing both shock absorption and great grip while cornering.
Cyclo Cross tyres are for use with road wheels to allow them to be ridden off road. They range from 30 to 35mm wide and are designed with different tread patterns to suit the various conditions that can be encountered during the Cyclo Cross season. Usually at the start of the season the ground is dry and hard so a narrower low tread tyre is needed as low rolling resistance is a priority. Later in the season when the ground is wet, grip is a priority so a wider tyre with increased tread would be the better option.
