Hi gang. I've been reading the recent "loosening Sliver shifters" thread with interest. Mine work fine, for the record... just keep tightening the front dérailleur side.
Anyway, my wife runs Dura Ace 9 speed bar-end shifters, mostly in friction mode. I recently changed the chain (about 1/16" long over 12"), and since then it very occasionally ghost shifts in the back. It sounds and shifts completely smoothly, otherwise, so I don't think it is the cassette. The problem is pretty darn rare, and I haven't been able to catch it in the wild, except maybe once. She says it will shift completely to another gear, either up or down. The one time I sorta saw it, it looked like the dérailleur actually moved. Unfortunately, her instinct was to immediately correct the problem by shifting back to the desired gear, so I didn't get to take a look. My brother suggested it might be a loose chain pin, so for starters I flipped the chain around. Hasn't happened again yet (if it does I'll try another chain), but if it were a loose pin, I'd expect the ghost shifting to be only in one direction, and that it would rattle before and after the shift as it tries to get back into the "proper" gear, so I doubt this hypothesis. I thought it might be a loose shifter (again, that would only explain ghost shifting in one direction), but I don't see how to tighten these shifters. The D-ring switches between indexed and friction (she says it happens in either mode), and so I assume the only tightening mechanism is the slotted-screw head at the shifter axle.... not sure I'm being clear, but that doesn't seem to be a problem either. I am flummoxed. Your thoughts, Oh Great RBW Community? -- You received this message because you are subscribed to the Google Groups "RBW Owners Bunch" group.
