New Carbon Disc WheelsetAfter much testing and finally winning the British Cross Country MTB Masters Championship in the capable hands of David Lines, we are proud to unleash these. A 30mm wide, 23.5mm internal width carbon Tubeless clincher. Low 1550g weight belies their capabilities. A great CX or MTB rim and can be used on the road with the correct tyres and pressures. For example, a 28mm tyre such as Continental GP4000 at 75psi works really well. We are using them with Continental CX Race and Speed 35mm - the latter being a surprisingly quick road tyre! Sapim CX-rays and a full range of hub options and axle standards.
