Putting on a new chain. First counted the links on the old chain - which I never had reason to think was the wrong length. But since I felt like being thorough I also measured using the largest cog to largest chainring method.
Largest cog to largest chainring comes up with a measurement 7 links shorter than my old chain. Advice on which to use? Is it possible my old chain was too long and I just never noticed? Don't want to end up with too short a chain.
