I'm looking at upgrading my current p.o.s. 8-speed crankset to a Race Face Ride XC with the 22-32-44 ring config. I have a shimano 8-speed cassette in the rear with a shimano deore long cage derailleur. My chain is SRAM and isn't super tight, it has some slack. I'm thinking it might be a 8/9 speed specific chain. I just want to be sure that I can use the 44-tooth outer ring with my 8-speed rear cassette.
