Just got back from my first ride on a pair of Crosswolf tires. I rode pavement (through San Francisco, across Golden Gate Bridge) to some nice fire roads in the Marin Headlands (Miwok, Bobcat trails). Did about 30 miles, 12 of which were on dirt. These tires rock! Very grippy and confidence inspiring in the dirt. Not too buzzy or slow on pavement either. The only other cyclocross tires I've used were Ritchey Crossmax which I took off of the bike pretty quickly because on pavement they felt pretty squirmy when cornering. I won't get a chance to ride in mud until the rainy season hits a few months from now, but so far, so good.
Anyone else use these tires? Before I bought them I couldn't find any reviews on the internet at all.
