Deda Elementi Parabolica Due Aero Bar Extensions

Deda Elementi Parabolica Due Aero Bar Extensions are clip-on aerobars for road, time-trial and triathlon riders who want a more aerodynamic riding position without replacing the complete handlebar. The Due uses S-bend extensions, distinguishing it from the Parabolica Uno and its J-bend shape. Riders wanting substantially broader extension and armrest adjustment can move to the more advanced Parabolica Pro, while the Due keeps the system simpler with three principal components and an included riser kit.

Built for Positioning. The S-bend extensions place the hands in a flatter orientation relative to the armrests, making the Due particularly relevant to riders who prefer a lower wrist angle in the aero position. Fully adjustable armrests allow the support position to be tuned around the rider, while the included riser system provides additional flexibility when a higher and more sustainable aero posture is required.

Check Bar Compatibility. The Parabolica Due clamps directly to a compatible round handlebar section and is not offered for every handlebar diameter. It should therefore be matched to the cockpit before purchase, particularly on modern aero-shaped or integrated handlebars where suitable round clamping area may be limited. Deda lists the system as UCI approved, making it relevant for riders setting up a road bike for sanctioned time-trial use as well as triathlon and aerodynamic training.
