The Gravel Grinder is our original and often-imitated fast gravel design. It combines a speedy diamond center for low rolling resistance with aggressive shoulder knobs that reliably hook-up when the terrain gets soft, muddy or a bit sketchy.
This handmade PRO version combines a supple Super Polyester casing with our durable SmartPlus Compound.
Challenge clincher tires are designed for use with tubes and hooked rims.
