Hi,
I have cube aim pro 29 with Altus M310 FD. Recently purchased, ready to run.
Thing is I'm not satisfied how the FD is working. There is a problem
with chain rubbing.
For ex. when running in second ring upfront (where in theory there should be no rub at all in any rear shift), there is a rub depending on cable tension.
If I adjust FD in the biggest rear ring, it rubs when I shift to small ones (7,8)
and vice versa. If I adjust in smallest rear ring, it rubs when I shift to biggest (1,2,3). So basically I cannot adjust that no rubbing is present in all rear rings when in second ring upfront.
Also in first ring upront I can ride only biggest four rear rings (1,2,3,4) with no rub. When I shift to 5 rubbing appears.
The height and angle seems OK. Also both limit screws are adjusted according to manuals. Is there anything else I could do???
