Has anyone every had a problem after installing new rearsets, that the replacement gear shifter doesnt fit as well as the original? I bought a set of alumninium GP shift rearsets (Ive seen the same ones from about a half a dozen companies- Im sure you all know what Im talking about. Anyway, rolling down the street, the shifter just fell off. Turns out the screw had worked its way lose. Ive order the part that was broken -the peg-thingy (bus ran over it) and have used antivibration super glue on the screw to make sure the thing doesnt work its was lose again, but still, confidence in the thing is now lacking.....Seeing as these rearsets (or very similar ones) are so popular I was wondering if anyone had a similar experience.
