Phinney:
If you do, I have a hot tip for you.
Comfort of the aero bars was dramatically (no kidding) improved with a higher bar position in respect to my seat height. I had a longer stem installed. I think about two to three inches. (adjustable)
This made it super comfortable. Now, if I could just get brakes up there (by my hands) I would be in bikers heaven on long trips.
