IDENTIFY A FEMALE-FRIENDLY BIKE FRAME?
Starting with the frame, the top tube is shorter than on a men’s bike, making for an easier reach to the handlebars. WSD frames are usually scaled down somewhat to account for more petite female riders, with sloping top-tubes to give more standover clearance in smaller sizes – allowing you to reach the ground when the bike is stopped.
A sloping top-tube also has the flow-on effect of a shorter seat-tube and more exposed seat-post, giving a little extra comfort through the rear end of the frame, as well as lighter frame weight on a women's bike.
Generally speaking, women have greater flexibility than men, so the head-tubes of a WSD frame tend to be shorter to give a natural position for the torso and hands.
