My shoulders measure 34. I had the Deda 4girls on my old bike but when I built my custom frame, and found out how narrow my shoulders are, my bike shop got the Modolo Venus in a 34. I love them, my arms are more in line with my shoulders when riding on the hoods. The best part, which is part of their design, is I can reach the brakes from the drops even though I use Campy Record.

There isn't much room on my handlebars for accessories but I don't miss the shoulder pain I used to have.
