I was looking for a picture in my facebook account and came across this picture from March 2010. I had been riding about a year by then, and had about 4,000 mi by this point. When I first saw this I was shocked to see that belly. I knew I had one, but it didn't seem THAT big. But then, I knew that it provided a nice bounce surface for my knees when I was riding in the drops. Something that I didn't do very much back then.
Note my race number (183) That was probably pretty close to my weight!
I don't have a comparable pose, but I think you can see from this photo that the aero-belly is gone. I was hoping at the time that the aero shape and the bounce affect were providing a benefit, and resulting in higher average speeds. That proved not to be the case.
My race number now should be 165!
