The Profile Design Sonic/Ergo/26a delivers a refined clip-on aerobar experience — combining the lightweight, low-profile Sonic bracket with Ergo armrests and A-Series extensions to give triathletes and time trialists a fast, comfortable position with genuine adjustability.

  • Sonic bracket offers an extensive fit range with minimal frontal area, keeping the cockpit clean and aerodynamic
  • Ergo armrests aid rider comfort during sustained aero efforts, reducing pressure points
  • A-Series 26° extensions allow fine-tuning of wrist angle independently of other fit adjustments
  • Aero-shaped extension section maintains the same 87mm rise as previous alloy models
  • New ergonomic end caps improve hand grip comfort in the TT position
  • 22.2mm extension clamp diameter with 7.5mm offset, compatible with standard aerobar brackets

The Sonic bracket is built around low weight and minimal frontal area — it holds a secure, adjustable position without adding unnecessary bulk to the front of your bike. The A-Series extensions introduced a critical new dimension: wrist angle can now be tuned without disturbing any other aspect of the fit. The 26° angle is the flattest option in the range, suited to riders who prefer a low, aggressive wrist position.

Compatible with 31.8mm handlebars. Extension clamp diameter 22.2mm. Pairs with Profile Design Plus Series armrests for further adjustment options.
