What size chainrings can I use on this Alfine crankset?
So I've got one of these. It's an Alfine FC-S500
Can I use any size chainring on this (assuming it's 5bolt). I'm toying with the idea of going from 45T to 42T to make things a bit easier.
I'm just a bit confused, as it says it's available in 45T (which I have) or 39T, so I don't know whether these are my only two options...
