FWIW, my old bike is a 54 cm Trek traditional/men's frame. My new bike is a 54 cm Trek WSD frame. The difference in fit and comfort is huge.
I had the shortest stem possible on the old bike but I was still hunching over and reaching too far in order to reach the hoods. On the WSD bike, I am able to reach the hoods while keeping my shoulders back and my back flat.
I thought the old bike was okay, not perfect but I could deal with it. Until I tried the WSD frame and realized the different geometry made a big difference. The WSD frame also has a smaller handlebar that is better suited to my hands.
I am 5'7" and I thought I didn't need a WSD bike because I have broad shoulders, long arms and what I thought was a long enough torso. I was wrong.
