Race hard or just go off the beaten track. The Strada Bianca combines the proven Challenge tread pattern with a higher volume, gravel-specific construction to keep you comfortable on less than perfect surfaces.

This tire is suitable for rough roads, broken dirt and most dry gravel surfaces. This TLR tire combines a supple 260TPI SuperPoly tire and natural rubber tread for long distance comfort, confident cornering and quick handling.

The tire incorporates the PPS2 system, which is a combination of our puncture protection system under the tread and an additional layer inside the tire to increase puncture resistance.

TLR = Tubeless Ready
Tubeless Ready tyres (marked TLR) can be fitted with or without a tube. TLR tyres are designed for tubeless use with sealant only and are optimally designed for hookless rims and are compatible with tubeless tyres at 33mm and above.
Challenge tyres should not be fitted to wheels that do not meet ETRTO or ISO standards. Non-compliant wheels can cut through the tire casing above the bead, resulting in tire failure and possible serious injury to the rider.
