Nah, I just fitted an X01 chain on mine. Was the first chain replacement since new, so it was almost 10 months old and stretched to buggery. The X01 feels nice, but I too am skipping on one cog in the middle of the GX cassette (also original). It's new cassette time.That's why I was mentioning the fact it's a KMC. Maybe I'd have been better with an eagle specific chain?
