So I'm going to start doing triathlons next season. I currently ride an '08 Specialized Allez Triple and will be upgrading it for my tri rides. I realize that there are clip-on aerobars available. However, if I chose a 1-piece aerobar set-up, would I still be comfortable on long [130+ km] rides using the bull horns? Does anybody do this/has anyone done if before? I rarely use the bottom/wrap portion of my road bars anyway.
