I am guessing - based on my commuting distances on a map - that I do about 70miles per week X4.3 weeks per month X 9months that'd be slightly over 1,500 miles if true.
Do you clean and lubricate the chain regularly?
I used to but after permanent grease on my clothes I stopped.
Are you some kind of freak cycling powerhouse?
Mmm, I wonder.
I'm asking because this would seem to be unusual in 9 months of riding.
Check your chain for stretch. Try to pull the chain away from one of your front chain rings, if you can see a fully exposed tooth, you probably have considerable wear.
