How hard is it to find the right cog+ring combo to create a chain length that'll work?
I keep reading on another forum people say that such-and-such a bike will need a tensioner, but I don't think so.
So, what's the math needed to find the right chain length for a cog-ring-chainStayLength?
(Let's assume a 0.5-1.0" vertical flex in chain movement)
