Upgrading the derailleur?
Have a ’12 Trek DS 8.3 with a Shimano M191 front derailleurand a Shimano Acera M360 rear derailleur.
Upon replacing the front derailleur’s cable, it seems the derailleurhangs and does not retract under its own spring tension. The derailleur is completely free of debrisand very thoroughly cleaned. The derailleurhas been lubricated after the cleaning leaving only one assumption left as aresolution, and that is to replace it.
My question is, what is the upgrade from the M191? I want to retain the same cable layout if itmatters yet increase the reliability (durability) of the derailleur. Since new, it seemed to have a sloppy up/downshift for the 48/38/28 crank set and if that can be resolved with a better mechanism,I’d rather do that now. The rear derailleuris fine, but if the alignment can be better supported to accommodate a newfront unit by replacing the rear derailleur as well, I am not opposed to thateither. Have an 11-32, 8 speed rear cassette.
