With the new setup, 38 alum aero bars and 140mm stem, I'm definitely more aero on the bike (I think). People tell me I look lower and more aero. There is still some question in my mind whether I can sprint as effectively with the new position. But I'm of the mind I can still practice and adjust to it. I've won my last 4 bunch sprints, so I'm thinking overall it doesn't appear to have set me back. And also I have been in a successful breakaway since the new setup. The other factor here is that I may just be racing with slow-ish guys, or guys on bad days.
