This tubular tyre is the result of Prime's collaboration with FMB, who are one of the world's top tubular tyre manufacturers. It offers the best balance of suppleness and low rolling resistance on your CX (cyclocross) bike.
A latex inner tube lowers the rolling resistance and at the same time offers better puncture protection.
Hand built in France using a natural cotton casing these tyres come factory installed with a highly water resistant sidewall coating.
