Challenge Gravel Grinder Pro Tubular Tyre

The Challenge Gravel Grinder Pro tube for gravel and cyclocross is a tyre that is suitable for gravel paths and grass or sand surfaces. The tubular version of the Challenge Gravel Grinder Pro is more reliable when it comes to punctures compared to a folding tyre. This is ideal for gravel roads with larger stones. It is better at adapting to uneven ground and this greatly reduces rolling resistance.

Smooth and low rolling resistance
This Challenge Gravel Grinder tyre has a cotton carcass on which the tread is glued. The cotton carcass makes the tyre very supple, and this makes it easier to ride through the bends. The diamond profile on the tread provides low rolling resistance and grip on a dry surface. The knobs on the side of the tyre provide the necessary grip when cornering.
