Turn your road bike into an aerodynamic triathlon machine with the Redshift Sports Quick Release Aerobars. The clip-on aerobars attach or remove in seconds (without tools) so you can instantly switch from road position to aero position. On a group ride or a local race? Remove the aerobars to drive a pure road bike. Do you take a triathlon or a long tour? Attach the aerobars and drive a comfortable aero position. The patent-pending quick release clamp locks the aerobars securely in the same position every time they are attached, and the integrated safety retention mechanism ensures that the bars stay firmly in place until you decide to remove them. Thanks to a wide range of adjustment options, you can ride in your ideal position. Simply change the width of the pad, the height of the stack and the reach of the extension elements, and choose between multiple expansion shapes to suit your riding style.
