Description : Does getting a new bike chain require getting a new cassete?
Last Answer : answer:Sounds like you do put a lot of wear & tear on the thing. If you're averaging 80 mi./week for 50 weeks of the year, that's 4,000 miles you've logged. Chains do indeed ... Especially around shifting, as cables stretch, need proper tension, and derailleurs need to be aligned just so, etc.
