Gravel Grinder is for cruising at speed and cornering with more confidence in soft and wet conditions.
The diamond center tread clears dirt and mud and grips grass and sand while the wide-spaced side knobs hook soft ground for traction and help guide the tyre through ruts. The mixed tread offers solid rolling resistance with a bit more cornering grip.
With vulcanised construction, Challenge starts where other tyres stop - the brand utilises ultralight 60TPI nylon casings and superior tread compounds - to give the traditional vulcanised tyres excellent ride feel and quality that is more affordable than the handmade offerings.
Challenge clincher tyres are designed for use with tubes and hooked rims.
