Another 5' even person here. I'm thinking you are more even than I am in the torso/leg ratio. I've have around a 29" inseam (measured crotch to floor bike style, not to the cuff like pants that is) so, I've got a short torso and even shorter arms. I have several bikes, two of them are roadies, one with 650 wheels the other with 700's, both have 165 cranks on them. If I look at the Spin Scan on the computrainer, contrary to a lot of popular wisdom, I am most most efficient on the 700 wheel bike, but that said it suits my particular body. For a short person I still have longer legs proportionally.
