asked by: a guest Will this M591 9-speed derailleur work on a 10 speed chain (I want to get a 32T on my ROAD bike, but need a longer derailleur to accommodate the 32T). Thanks.
A.
anwered by: canteau The M591 rear derailleur should work with road bikes using older Shimano 10-speed drivetrains.
Newer Shimano Tiagara shifters do use a different cable pull and are not compatible.
