replacing Stronglight crank with Campy: Problems?
I'm a new poster here. I am restoring a 1973 motobecane grand record, and its looking pretty good. The chain slips off the largest gear of the freewheel, and I figure they just both need to be replaced. I got an old atom french thread freewheel on ebay, and I'll get a chain too. When I watch the largest gear wheel turn I can see that it does not turn in a perfectly flat plane, so it rubs the side of the front changer. I'm thinking the gear wheel is slightly bent. I'm wonding if I can stick a campy crank on the stronglight axle, or will the two have compatible angles or dimensions or something. Has anyone had any experience putting campy cranks on a stronglight axle? I know every other component on this bike has odd sizes, why should the axle be any different?
