Deda Parabolica Uno Clip-On Extensions

Deda Parabolica Uno Clip-On Extensions are a clean, lightweight solution for adding a stable aero position to a standard road cockpit. Designed for riders targeting time trials, triathlon, or fast solo efforts, the Parabolica Uno focuses on comfort, adjustability, and simplicity—making it easy to build an aero setup that’s effective and repeatable.

The extensions use Deda’s classic J-bend (Uno) shape, promoting a natural wrist angle that reduces strain during sustained efforts in the bars. Constructed from 6061 aluminum alloy with 24 mm extension tubes, the system balances durability with a tidy, race-ready feel. Forged alloy clamps keep the interface secure under load while maintaining a low-profile look at the cockpit.

Armrests are fully adjustable for width and fore/aft position and include comfortable pads to help you stay planted when the effort ramps up. The Parabolica Uno is designed to be easy to dial in, allowing riders to focus on holding a strong aero position rather than constantly shifting to stay comfortable.
