Thanks for the input everyone. I've ordered as I said above 16t fixed and 17t freewheel with my 52 front. I'd read that somewhere around 70" seems to be the preferred road setting, but I live by the seaside, where it's very VERY flat. I can do 30+ miles and not climb 100ft on certain routes - and definitely not where I'm planning on taking this bike.
