Yesterday, I went out in the garage to do a ride, and my rear tire was flat. So, since I had to fix the flat anyway, I thought I would remove my commuter fenders as I will not be commuting to school for three weeks or so, and while I was at that thought I would go ahead and do a clean-up, degreasing, lube, and tune. When I looked at the rear rim, I noticed a 3-inch crack in the rim and a bit of a hole surronding one niple hole and annother smaller crack near on other hole. Oddly, the rim was still pretty true. anyway, I figure that the rim was near catistrosic failure, so the flat may have saved me. Off I went to the bike shop, a rim, 32 spokes, some handlbar tape rim tape and an innnertube richer, as well as $95 lighter in the wallet, I learned that I can still rebuild a damn fine wheel in less than an hour. Rode 40 mile on the new whell today, true and round after the ride as it was before the ride. Lat time I built a wheel was in 1978...I am pleased and proud that thats one skill that has not left me.
