Start shopping for your next chain now. The XG-1275 is my preferred cassette and I have it on both of my Creo's. Poor chain maintenance will eat up an expensive cassette in no time. I recommend the
SRAM CN-EAGL-X01-A1. I personally wax my chains every two or three weeks depending on miles. Whichever lubrication system you use, keep up on it and don't just ride and forget about it. You will wonder why three months later your shifting is awful and the cassette needs replacing along with the chain.xxg-1275 xg
