thanks!
i'm 5' 3/4" & just bought an extra small frame which fits me perfectly. i have a short torso & long legs. i'm new to the road bike thang (i'm an xc rider by trade) but the way i understand it, you don't want to be over-extended when reaching for the handlebars.

giant bicycles has a convenient sizing chart on their website. hope this helps!
enjoy!
