Have about 9 000km on a XO1 casette and XX1 chainring. I have been rotating three chains (2 x XO1 chains and one GX chain-which I took out of rotation, because of higher wear). I have now had a few chain drops and I am thinking of only replacing the chainring and see if that solves the problem. Should I consider getting two new XX1/XO1 chains to start with the new chainring and hope the casette is still ok, or do I just continue with the current 2x chains till the casette needs replacing?
I guess it will probably depend on the wear on the chains....and If they are still within the 0.5% then replacing with two new ones should be ok, if over 0.5 then probably to late..?
Would you agree with my logic and which DM chainring would you suggest?
