Pondering a change from 9 to 10 speed and wondering about compatability of rear mechs, shifter, cassettes and chains.
I'm currently set for a 1 x 9 with an oldish 11-34 XTR cassette, 9 speed HG93 chain, new m970 shifter and matching rear mech but would like to gently upgrade to a 1 x 10 setup. Obviously the shifter and cassette will need 10 speed bits but would the chain and rear mech still work in such a setup ? The front ring is a Cannondale (FSA) Si type so presume that'll be ok with a 10 speed chain if I need one ?
Also contemplating whether to switch to Sram X0 but heard it can be rather clunky compared to XTR but rather like the carbon on the X0 kit.
