Yes, aero bars. They're actually comfortable if don't get a set up that's too aggressive. It's really nice to take the pressure off your hands for awhile. Some of them can't be mounted along with a handlebar bag. I found them stable even with a fully loaded touring bike, but then I don't sit in the aero position unless the road is pretty mellow. I know it looks silly and people will laugh to see a fully loaded bike with aero bars, but, man, they're a big help in the wind and when your hands begins to hurt. Sometimes, you might feel like you could even nap in that aero position.
