I'm 5' 1" and ride the second smallest road bike that Terry makes. I'm betting that their smallest frame would fit you well. Terry designs bikes specifically, and only, for women. Georgena Terry designed a semi-custom road bike for my mother last spring. Mom is also 5' 1". Her new Terry is the best fitting, and smoothest riding, bike that Mom's ever had.
