Was a long time Donlley/Clemente rider but since I can't get those anymore I needed to find a replacement, and the Challenge Grifo are them!

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.

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.
