I'm 5'2", and I have a Bianchi Eros Donna in 44 cm and a Colnago CLD in 40 cm that fit me perfectly. Both bikes have 700c wheels, standover height of about 27", and almost the same actual and effective top tube lengths as the Surly Straggler 650b. It's a shame Bianchi stopped making WSD steel bikes and now only makes 46 cm bikes or bigger since the smallest 44 cm Eros Donna with small Campy ergo shifters is a perfect bike for us Wee-Folk.
