I am 66" tall... What is that in feet? i thought i was 5 foot 7 or 8.. I have a 31" inseam

so what size road bike would i ride then? I have been going by the 5 foot 7 height? would a 54CM frame be too big for me then

or 65"

I was going to spend a bit money on a bike today... just double checking.... this chart says 54cm. http://bicycling.about.com/od/howtor...ike_sizing.htm
