The Challenge Gravel Grinder TLR Folding Clincher Tyre is designed for long rides over gravel roads. Thanks to the Puncture Protection System it is also suitable for a rougher everyday use. The flat tread in the middle keeps the rolling resistance low while the higher side knobs offer the needed cornering grip.

This Tubeless Ready folding tyre with a 120 TPI casing made of nylon is very supple and comes with a Puncture Protection Strip (PPS), which is an extra layer of highly resistant material between the casing and the tyre to reduce the risk of punctures.
