current setup is Shimano M-615 SGS rear derailleur, Shimano Deore M591 shifter and Shimano CS-HG81-10 11-36T cassette
My idea is to return to 9-speed while not throwing the derailleur. Wanna change the shifter to SunRace M95 (9sp shimano compatible, dunno if pull ratio should be changed to be DynaSys compatible) and some 9sp cassette with alu spider (the hub has alu freewheel body) or at least to remove one of the cogs.
Any ideas if the 9sp shifter will work with the 10sp derailleur? Thanks in advance
