I’d recommend you stay with the women specific models for some of the same reasons others pointed out.

My wife is the same height as you and she needed to go to the women’s Trek Domane in order to get a size that matched her short inseam and reach. She’s comfortable on the size 47cm frame, which is smaller than the smallest men’s frame. She also needed a shorter stem than what normally comes in men’s sizes.

Chances are you’ll need to go with the Avail in XS for the best fit.
