Bicycle Mechanics - Shifter / Derailleur compatibility
09-21-05, 09:38 PM I am thinking of changing my eight speed
cassette to a nine speed and changing the Acera derailleur to a
105. One question though, will my current gripshift (set up for
the eight speed cassette) have to be changes as well or will it
work? Thanks.  09-21-05, 09:42 PM A 8 speed shifter isn't going
to work a 9 speed casssette.
