More Information

Challenge Almanzo Pro 700c Clincher Gravel Tyre

The Challenge Almanzo Pro is a handmade clincher tyre, designed for off-road gravel riding. The tread pattern is such that it allows you good traction on hard pack dirt and loose gravel surfaces. Ideal for adventure riding or commutes where sections of your ride are off-road. The casing is Challenge's SuperPoly compound, which is a durable polyester material that is lightweight and strong. Beneath the casing are two layers of puncture protection to reduce the risk of flats.
