Profile Design ADL Aluminum Clip on Aerobars

One of the first cyclists we noticed using extensions with an S bend shape on bars like the Profile Design ADL Aluminum Clip on Aerobars in a time trial was Ullrich, the German powerhouse and perennial Tour runner up. That's no surprise, as riders like Ullrich built their careers on producing disproportionate watts, and the ultimate purpose behind S bend bars is to provide more leverage while you're stretched out on the extensions. It's true that this focus on force comes at the cost of cornering and precise handling when compared to traditional, upturned aerodynamic extensions, but that's what bullhorn brake extensions or hoods on a drop bar are for. During long, non technical grinds against the clock or triathlons when pure power is the deciding factor, the S bend is the way to go.
