New wheel / cassette & grinding

Ive just upgraded my wheels to Mavic krysiums and fitted a SRAM 10 speed cassette. This changed from ritchey wheels with a 10 speed shimano cassette. The rest of my group set is all SRAM Rival, with the exception of a shimano chain so assume compatability won't be an issue.

I noticed a grinding noise coming from the rear déraileur. I've adjusted the limit screws and when turning the pedals backward & forwards with no pressure runs smoothly, however it seems to grind as soon as any pressure is applied?

Prior to the change it was running very smoothly.....any suggestions?

    Have you put the chain through the rear deraiileur properly? I managed to make it go outside the lower cage once.

    When you say grinding does it grind like it wants to change gear?
  • Could be that the chain-line is now out. Check if the grinding is more when the chain is at an angle. Better to measure the chain-line to be sure.
