debatable.

I never had a KMC chain, but I had this big gold bmx chain made by SRAM (PC7X I believe) and it just barely rubbed. I just took out the pulleys and bent the cage out a bit where the chain slides through, then put it all back together. It worked fine for me until I put my PC99 back on :).
