I have aerobars on my road bike that I really love, It's really quite comfortable and I really get more power to the wheels in that stance. I'm probably going to convert my current commuter into a TT type bike when I get a new road bike in the winter since I have almost everything I need to do the conversion except another set of aerobars and bar-ends, and I'm going to be doing the bike leg of several team triathlons next spring, (If I can lose enough weight to start running again I'm gonna do a half by myself
