I just built up a 1982 Trek 614 as a touring bike and while riding today noticed that 2 of the tabs in which the chainwheels bolt onto the crank are bent. This causes the chainwheels to move in and out as you pedal. I might be able to straighten them out, haven't tried yet. But if I can't, does anyone know what a good replacement would be? The original is a Sugino AT. I don't know anything about cranks and want to make sure I get the right size. Does it even matter as long as it is square taper?
Thanks for your help!
