Description of Challenge Gravel Grinder Plus Folding Tire - 622

This tire 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 folding tire with a 60 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 tire to reduce the risk of punctures.

Available in various widths.

Fantastic for mixed road for my CX bike. Excellent grip in curves and a bit loose surface (sand, mud). I am using with 4.5 BAR tyre pressure and satisfied with it.
