I have a dedicated tri bike and I have aerobars on my road bike. The ones on the roadie are the "cheap" Profile Designs ones that have the flip up pads. I love having another position on long rides and I love the almost free boost in speed on the flats. They are somewhat heavy, but these aren't on my racing bike, so I don't really care. I would recommend them. But DO NOT use them in group rides. They definitely cut down on your ability to make quick moves and on your bike handling ability.
