As you know, I had managed to pull an old 1941 Hiawatha (Shelby Flying Cloud) bike out of the weeds in my own backyard. Well, I had been thinking some possible directions to go with it. One involved simply using 1960's schwinn pedal cranks and pieces to replace the rusted pieces. This got me thinking. Has anyone did a 10 speed conversion on a prewar bike? I have several junked mountain and road bikes, and I found an old 1980's Huffy 10 speed mountain bike with good cranks, rims, and derailleur. It's all chromed, and it has the older style levers by the handlebar stem. I do plan on riding it often.
