Gravel Grinder Cross folding tyre

Thanks to a flat diamond-style centre tread, the Gravel Grinder by Challenge rolls incredibly smoothly. Besides, higher side knobs offer sufficient grip and cornering stability on cross trials and in races. The tread pattern of the lightweight cross tyre is especially designed for rocky gravel paths or sandy ground for high speed gravel rides. Puncture protection included. The all-rounder neither stops at hard nor at moist grounds and safely and nimbly gets you over the track. Last but not least, the Grinder Race offers outstanding traction.
