My goal is just to get this bike up-and-running, as economically as possible. I _did_ splurge on the Cyclone derailleur. But having, for instance, to build out a new rear-wheel would kill this project for me.
I wanted to replace the Regina freewheel because I had a heck of a time pulling it off, and I wasn't the first. The "tabs" that form the notches the removal tool fits into are chewed up; if I put it back on it might be for the last time. (And by the way, it's 13-15-18-21-24.)
I might have gotten overly ambitious, because I removed the axle and ball bearings from the rear hub (the hubs are Campagnolo) and after I was done I looked at it wondering how I'll ever get it reassembled.
I have not disassembled the front hub yet, and am thinking I might not.
