I've been riding this bike for over 25 years. The hubs, BB, crank set, and most everything was installed summer of 1989. It's a rock solid bike. I still have fun riding it. The following are some of the parts I put on the bike:
Phil Wood hubs and BB
Cook's QP crank set
Cook Brother's Racing stem and handlebars
All Deore XT (XTR front derailleur)
