Right, so far changed the cable inner, then the outer, then removed and cleaed the dial etc, nothing has worked so far.
As stated above and on countless threads on various forums it seems the return spring may be to blame.
So two options, 1/ look to replace the sping, if I can get to it and find the part, or 2/ just replace the "remote dial" with a manual dial and bin the poploc nonsense - although I do like the idea of handle bar located remote when on rough trail.
Where is the best placed to source these parts, I imagine changing the dial is easy, but not sure on changing spring(s)?
