    AC Sizing 17" or 18"

    I'm buying an AC1 frame to build. I am 5' 8.5" and 180 lbs. My inseam is only 28" and I have a long torso. I've been on a 17" AC1 bike but am wondering if it is too short for my torso. Would I be able to straddle an 18" frame comfortably?

    Small: top tube is 565mm, seat tube is 430mm
    Med: top tube is 585mm, seat tube is 455mm.

    So I assume the stand over is 7/8" taller and the reach to the handlebars is 3/4" longer on the 18" medium frame.

    Hope that helps. Have fun,

    Chris
