Price update. This mech will work with any type of Shimano shifter (might have to be 9 speed though...not sure). Rapid rise just makes the mech sprung to the largest rear cog instead of the smallest.
Just bought another XTR Rear Mech (conventional rise) so this reeeaalllyy needs to move onwards (as I will never use it).
Any offers before I stash it away or show it to the dogs of ebay!
