Since we can't thank him personally any more, it seemed right to post him some thanks today on the forum. I've probably learned more from him re bike repair than any source I've ever encountered.
Last summer he was my source when I rehabed a 1960's BSA 3-speed.
This week it was a 1990's Trek mountain bike with a cross-threaded (right-hand) bearing cup stuck in the bottom bracket. I was ready to try a big adjustable wrench on those skinny wrench flats, until I thought, "there must be a better way," and I checked Sheldon Brown. If you haven't tried his universal fixed cup tool, it's brilliant and it works perfectly! It's just a 5/8 bolt, nut and washers. You also need a hefty socket wrench, or in my case a socket and breaker bar because that fixed cup was really fixed. Now Im ready to install a threadless bottom bracket.
Thank you, Sheldon, for another old bike on the road.
