Aero bars. They are only good for time trials, full out racing. Its not all that easy to steer, the body position is not the most comfortable and definitly not made for sprint. If you look at the sprinters position when they are on all out sprint, their hands are almost always on the bottom part of the drop handle and pulling really hard on the handle bar. You can't do that on a aero bar.

I would have an aero bar on Quintan Roo Caliente or Lucero (or litespeed Saber)with cow horns but then the bike would strictly be for TT. Just my dream bike #2.

Aero bars may look spiffy but I wouldn't recommend it.

just my 2cents
