I have a bike with a ratio of 3.11 to 1, how many links do i need in a chain? I legit just broke my bike chain riding it. One of the links just snapped and i wanted to replace it with a brand new chain that will hold up better. How many links do i need in that new chain so that it will fit on my bike?
