Losses in watts from worn drivetrain?
How much do I lose in watts when I let my chain and cassette get worn. I'm not sure how stretched mine are right now but when I'm going really hard I'm starting to hear more sound even when the chain is lubed. Yes, I could measure the stretch. But I'm wondering about how much are the losses as a system gets worn, as measured in watts. I'm not talking about the maximum of badness of a ruined system. Just as a drivetrain wears, what happens to its efficiency? Thanks.
