There was a (pretty strong) guy wearing a local tri-shop jersey at the Tuesday Nighter last week, riding with aero bars -- in the A group. There was a minor break about 50m up the road, and the pack was just letting them hang out up there.

This guy decides to get into his bars and pick up the pace. Granted, he was moving pretty fast (passed right by the break), but as soon as he was done, a couple of the big guns attacked, and that guy was spat out the back of the pack with his aerobars. I think it was an intentional move by the riders that attacked. Their break didn't stick, and I really think they did it to get the aero bars out of their pack.

I dunno, it doesn't bother me that the bars are on somebody's bike (just stay out of them if you're drafting), but if it's a TT bike, handling is greatly compromised in corners -- and that bothers me. Of course, the Tuesday Nighter is a training race, so on a normal group ride, high-speed cornering isn't necessary.
