I recently overhauled a Cannondale that a friend of mine had been given by his brother. Weird mix of parts (some incompatible), very much in need of overhaul. I needed to replace one of the bearing cones from the front wheel, and the old one was just crazily pitted. Pitting covered about 5/8 of the race. The intracacies of the pitting are pretty impressive. Also, the axle was difficult to turn when holding the locknut between thumb and forefinger (the wheel itself was heavy enough to turn for awhile under its own momentum, when mounted on the bike).
