I've gone 1*10, with a SRAM cassette and mech and old XT cranks.
I'm running a KCNC downhill chainring in middle ring position with a KNC 10 speed chain.
The setup changes very well, (gripshift up front), however the chain doesn't seem to mesh well when I'm in the largest two sprockets, it seems to be pulling a little.
I put a spacer in between the chainring and the spider and now its only the largest sprocket that doesn't mesh well.
I guess I'll try adding another spacer, however is this normal to need spacers?
