The Challenge Grifo Open tire combines a tried and true tread pattern with the versatility and ease of use of a clincher that's perfect for racing and training. At 300 threads per inch, this tire is remarkably supple for a clincher. Low profile knobs are great on fast grass courses and hard packed gravel/dirt, but aggressive enough for mud. If you could only have one clincher for the entire season, the Challenge Grifo would be a great choice.
Note: This tire is somewhat confusingly labeled as an 'Open Tubular.' It fits standard clincher rims.

Great all around cross tire
Fast tire on hard pack and grass. Not stellar in the mud or sand, but still steady on gravel rides. A mate pairs this with a mud tire up front but I'm running them front and rear.
