I have some old size 630 wheels on my mid-80's panisonic. I'm looking to get a new set FSA wheels, However they don't sell, and in fact i've been hardpressed to find size 630 wheels in any brand I've looked. I need to know whether or not I could stick 700C on them without trouble. Or If there is some other size that would do well. Any help would be great. thanks a bunch.
