Even when I did a lot of mountain biking, about 5,000 miles a year I went through chains about every 8,000 to 9,000 miles and the cassette would always last about 3 times longer than a chain, with the chainrings lasting about twice as long as the cassettes. So how many miles do you ride a year? are you a pro or semi pro rider?
