Challenge Handmade

Handmade tires combine many attributes to create the most comfortable and low rolling resistance tires. Handmade Clincher tires perform better than any vulcanized tubeless system! The HTLR is molded flat. This shape allows the casing to naturally deform over surface imperfections and minimize rolling resistance.

PPS2

The Puncture Protection Strip is a special fabric placed between a tire's tread and casing to increase resistance to punctures. Some tires deisgned for rough roads use and gravel have an additional protection layer between the casing and the inner tube.
