I also wouldn't go strictly by the "frame size"; compare the stack, reach, and standover heights of one of your current bikes to whatever FG you're considering. Sometimes a 53 is really a 55 (and vice-versa).
I'm aware of how to measure and size a bike, but I'm not going to call FB/CL listings and ask them to measure the stack and reach on a >$200 fixie. Wouldn't be worth the frustration.
I was more asking along the line of whether
with regards to F/G if it's better to have a bike that's a little on the small side, than too large. I figured, since you can't stop pedaling, that it'd be preferable to have the clearance of a little smaller bike between your knees.
