Description
The All-Around Best
The Challenge Grifo 33 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 and requires a tube.

Reviews
These tires are excellent. Mounting these tires will have you breaking tire levers and questioning your existence. But when they're mounted and working, these tires are hard to beat. Surprising durability compared to how soft and grippy they feel. Tan sidewalls will discolor permanently after a few muddy or dirty races, but that's fine. Would recommend, but get help with mounting.
