I could not believe how much my chain had worn after only 8 weeks. But due to the really muddy sandy gritty conditions I had been riding in, 100 miles a week and struggling to clean it after each run to work it just got eaten. AND having only just replaced all the cogs I did not want them to get eaten too. I can go through 3 to 4 chains on each set of cogs and remember, chains are cheaper than cassettes and chain rings! :)
