Shifting problem

[Catrin]

Um.

What's the second cable?

The one I was talking about was the one in the pictures on this page.

It's possible your high limit screw is too close, keeping your FD from moving as far from the frame as it needs to when you're in the big ring, if tightening the cable isn't having any effect on that end. I wouldn't have expected the LBS to get that wrong, but it's possible. The page I linked to also has instructions for setting the limiter screws. It's also possible that you're at the limit of your barrel adjuster and you're just turning the loose end inside the housing, in which case the cable will need to be re-positioned in the clamp (again - which would be strange).

Anyway, I think you made progress? and learned something about your bike? and it isn't worse so you can still ride to the LBS? if so, good.

That looks like the correct adjuster (as long as it's the cable that goes to the FD), but I still don't know which other cable you're talking about?

I could not seem to get a good shot of both - but there are two barrel adjusters on both sides of the down tube. I assume the other one goes to the RD? It isn't the brakes - that runs under the TT, so the second one MUST go to the RD.

I turned it upside down and that is indeed the case, one cable (and adjuster) per derailleur. I adjusted the wrong one Let's try this again
