While cyclocross is typically seen as a wet and muddy venture, some courses require a tire built specifically for sandy and hardpack conditions. Challenge's Dune tire is just the ticket with tightly packed pyramidal center tread and larger blocks on the shoulder tread for fast-rolling performance and excellent traction when the course gets sandy.

Paired with extremely high TPI thanks to Challenge's Silk natural fiber casing, this tire is incredibly supple and allows for more precise handling and a greater range of pressures.
