When I bought my new Trek hybrid I decided to come into the 21st century and stop using oil on my chains and switch to wax based lubricants. At 830 miles since new my chain (KMC) is worn out and I have today replaced it. 830 miles is taking the p**s. On my old bike my chains lasted far longer with regular cleaning and good old fashioned oil. My new chain is going back to oil. I haven't checked it on the road yet but I am hoping my cassette isn't stuffed after such a low mileage, although 8 speeds are not too expensive thankfully.
