Today I went to the University of Maryland bike co-op to help a friend tune up her bike. As we were leaving, I noticed the guy who works there was building a fixed gear wheel. So I said to him, "Hey, fixed gear wheels, eh? I've been meaning to build a pair, but I need to get another 32-hole rim." He tells me to check under the counter, they've got a bunch of old rims...

I hunch over and look under the counter, not expecting much. There's a forlorn heap of wheels and rims. Mostly 26 inch and 27 inch. Most are single-walled and some are warped. Then, I find a nice-looking double walled rim. Yep, it's a 700C Sun CR-18 double-walled rim... drilled for 32 spokes, with hardly a sign of wear on the brake track, about the most solid rim known to mankind

Gosh, I love the bike co-op...
