Pre winter my front derailleur worked fine- perfect in fact, but in the last few rides it has been playing up with chain rub without my having done anything to it to cause it to happen.
It has now got to the point where in the middle (triple) ring the derailleur is catching on the teeth of the large ring, does the derailleur have an 'up' movement or is it just side to side? Have I used the inline adjusters to pull the cable making the mech too far over? or is the whole thing just a bit seized and should be attached with some WD40 and some repeated shifting to loosen it all.
I'm thinking the latter as if I shift up from the granny ring or down from the big ring the mech will sit in a different position- surely it should be central no matter which way I've come from?
