One versatile clincher to ride all season.

Challenge's Grifo Open tire features the tried-and-true Grifo tread pattern, with low-profile knobs that are not only great on fast grass courses and hard-packed gravel and dirt, but aggressive enough for serious mud. Plus, at 300 threads per inch, the tire is remarkably supple, so you can focus on your race instead of the harshness of the terrain. 700c x 33mm.

Note: This tire is somewhat confusingly labeled as an 'Open Tubular.' It fits standard clincher rims.
