[RBW] Re: Bar End Shifter Woes
I ruined a Silver shifter by removing it while the cable was still on. I got away with it a few times but eventually the cover of a ratchet mechanism bent and it was toast. If I have to remove one I now always unbolt the cable clamp at the derailleur. -- You received this message because you are subscribed to the Google Groups "RBW Owners Bunch" group.

I wouldn’t be surprised. As far as I can tell the original Riv silver shifter and the Gran Compes are identical—probably made in the same factory—and they seem to have failed in the exact same way. -- You received this message because you are subscribed to the Google Groups "RBW Owners Bunch" group.

I wonder if it is partly the inferior quality of metal used in the small bits these days that make products like this more susceptible to this kind of damage. I've never had a problem like this with Sun Tour or Shimano bar ends. That could also be due to design difference, but I thought the GC EnE was a copy of the ST.

Hi, Brady, I do put lubes on the cables when I install them new. For the specific problem you described, One thing you could do is to put some beeswax on the cable end (the knob) and then pull the cable snug. I do have some spare shifters, will PM you to see if you would like to buy them.
