Hi all,

im having a nighmare setting up a 1×12 setup. Clockwork evo frame, slx 7100 12spd 10/51 speed cassette on dt boost hubs. slx shifter and xt m8100 sgs rear mech. KMC x12 chain. Cranks are standard non boost with 12 spd n/w chainring on them. Ive set up loads of rear mechs and was expecting buttery silence when installed. I cant even get the chain to roll around the cassette without trying to jump onto the tooth inside it. Lots of ghostshifting from cogs 11/12, wont index well. lots of crunching and grinding. Im aware that these rear mechs lower cages arent quite straight but mine looks all over the show. When on the smallest 10t cog the rubber bumper that sits on the back of the lower cage is about 10mm outboard of the chain, i thought this was to prevent chain slap, they dont even line up. Can anyone offer any advice or have pick of your 12speed mech from behind, as it is its non rideable. Im thinking ive missed something really obvious but have rechecked every thing, are KMC chains ok with slx cassettes?? thanks for any help
