Fuji Track / Fuji Track Pro / Fuji Track Classic

Anyone able to give me a shout on these size wise. Was looking for a 58 being 6' however, I have seen a cheap 56.

How would a 6' chap ride on a 56, would it be cramped?

Thanks.

I'm about 6'2 and ride a 56, much too small, although the noob in the shop insisted it was the right size, i knew little about bike sizing at the time.
