Spidermonkey on wheels
I just bought my bike in July and I have been having a mechanic check the wear of my chain seeing as I don't have a tool. I just now has gotten to 1.0% wear so I replaced the chain. The new chain bucks about once a pass when I put pressure on it. The guy at the LBS insists that my cassette is worn too bad but I think he just wants me to buy another from him. What do you think/suggest?
