My favorite hands down.
I rode my bikes with road bars all week then rode my road bike with these. Out of the 6 road bikes I own 2 have these. I might change all my bikes to these. They're not for everyone cause you have to ride the drops in a pack and they're low. But the aero position is comfortable and really allows you to rest. Here's a pic of mine and triathlon champion Mike Pigg on his.
