Deda Parabolica Due 31 Clip-On Extensions

The Deda Parabolica Due 31 Clip-On Extensions bring an S-bend profile to riders who want a more natural wrist angle in the aero position — the two-curve shape of the Due bend positions your hands lower and closer than a flat or J-bend extension, which can ease shoulder tension on longer efforts. At 300mm in length and 300g, they're a compact, no-excess option for triathlon, time trial, or any setup where frontal area and fit precision matter.

The aluminum clamps mount to 31.7mm handlebars and use two bottom-access bolts, keeping adjustment clean without tools sticking up above the bar. Adjustable armrests move fore and aft as well as laterally, so you can dial in pad position without swapping parts. An armrest riser kit is included with the 31.7mm diameter — three spacers (10mm, 15mm, and 30mm) that can be used individually or stacked, letting you tune armrest height to match your position. Pads are included.
