Deda Parabolica Zero Clip-On Extensions

The Deda Parabolica Zero Clip-On Extensions are a flat-bend aerobar extension designed for riders who want a direct, low-profile position on the bike. At 310mm long and 396g, the Zero is the longest option in the Parabolica range — suited to riders who prefer a straight reach to the bar ends rather than a curved or S-bend profile.

The aluminum clamps mount from the bottom via two bolts and include a secondary round clamp to lock the extensions securely in place. Adjustable armrests move fore-aft and laterally, and pads are included in the box. The extensions are available in two clamp diameters — 31.7mm and 35mm — to fit standard and oversized handlebars. The 31.7mm version includes an armrest riser kit with 10mm, 15mm, and 30mm spacers that can be stacked in any combination for additional height adjustment; using all three spacers adds 140g to the total weight.
