Challenge Gravel Grinder Vulcanized Gravel Clincher Tyre

Challenge Gravel Grinder Race Vulcanized Clincher Tyre

Fast and light, Challenge’s Gravel Grinder Race Vulcanized Clincher Tyre is a great option for smoother, hardpacked trails, where the central file tread reduces rolling resistance for easier speed. Much more aggressive side knobs allow it to bite when cornering and give it some purchase in softer conditions. The Puncture Protection Strip, made from tougher fabric, sits underneath the tread rubber and prevents sharp objects from penetrating the tyre.
