Retapping derailer's cable clamp?
I got hold of a Superbe Pro RD that was extremely rough, cleaned it up a bit, put it on a bike and discovered a bigger problem - the threads inside the clamp for the cable are stripped. Does anyone happen to know what size thread/pitch the original bolt would have used? I'm not convinced the bolt that came with this unit is the right one anyways, would like some suggestions as to what size tap I might best use to correct the problem.
