I have the identical problem on my Davidson, with a 12-34 9 speed cassette matched to a 24-36-46 triple. The guys at the LBS tried everything, replacing each part, replacing all the parts, lubing, relubing, and readjusting the derailleur.
My problem is the same that you describe : the derailleur can be adjusted so it does well with the three largest, or three smallest, cogs - - but not all 9. This is a deeply perplexing issue, since the identical drive train on my Bob Jackson shifts just fine, dandy. For now, I have replaced the bar-end shifters with Paul Thumbies, moving the shfiters up on the top of my handlebars. Not as convenient, looks odd, but shifts somewhat better. The chief mechanic, Loathsome Fritz, thinks the problem relates to the long cable runs. Shortening the cables by moving the shifters up top seems to help a little. Still not perfect. If you can figure this out, I will be grateful for whatever solution you can come up with. RL -- You received this message because you are subscribed to the Google Groups "RBW Owners Bunch" group.
