8 speed shifters work with 9 speed deraileur/casette?
I'd like to upgrade my casette / deraileur to 9-speed for now because my casette is worn and i have to replace it, so might as well make the jump from 8 to 9 speed.
however, i don't have enough cash to drop on new shifters, so can i just use my old deore 8-speed shifters with my new 9-speed setup?
