Profile Design Sonic Ergo 43a Aerobar

The Profile Design Sonic Ergo 43a Aerobar offers a neutral wrist position with the forearms lying along the extensions for greater aerodynamic benefit. A wide range of adjustment is possible to allow a powerful and wind-cheating position to be dialled in with both the width and the offset able to be altered.


  • Great option for any rider looking for a neutral wrist angle and positioning versatility
  • The 43a is an enhanced version of the popular t3 extension
  • The Sonic/Ergo platform offers a large range of adjustment in every dimension, enabling riders to optimise the comfort of their position
  • The 43a extension offers a wrist relief style bend that is intended to allow the extension to hug to the arm for improved aerodynamics without sacrificing wrist comfort
  • Fit range:
  • Armrest Offset -70mm to -17.5mm in 7.5mm steps
  • Armrest Width 124mm to 290mm in 18.5mm steps
  • Armrest Stack 60mm
