Deda Parabolica Uno 35 Clip-On Extensions

Deda Parabolica Uno Clip-On Extensions are a streamlined, lightweight way to add a stable aero position to a standard road handlebar—ideal for time trials, triathlon, or fast solo work where staying low and steady matters. Deda keeps the concept simple and effective: a J-bend extension for a natural wrist angle, a forged alloy clamp for a secure hold on the bar, and an adjustable armrest platform designed to help you stay planted when the effort ramps up.

The Parabolica Uno uses 6061 alloy construction and 24 mm extension tubes to balance durability with a clean, race-ready feel. The armrests are fully adjustable and come with self-adhesive hook-and-loop pads, letting you fine-tune comfort and support so your aero position is sustainable—not just aggressive for a few minutes at a time.

Choose the clamp size that matches your cockpit: 31.7 mm or 35.0 mm. For riders using the 31.7 mm version, Deda includes a spacer kit that allows you to raise armrest height by up to 55 mm, making it easier to build a position that fits your flexibility, fit targets, and race goals.
