Profile Design Cycling / Bike 4a Aerobar Extensions - 400mm
The new range of extensions have evolved from our well proven T-Series. They have been designed to offer distinct fit options. We have also adopted a new naming system whereby the name gives the angle material of the extension. Thus 43a is a 43° bend in aluminium.
Performance
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.The 43 degree grip angle is based on testing with riders to find a common neutral configuration.
Fit Data
Orgin
Profile Design had great success with the T3 extension from our previous range of bars. The 43a is an enhanced version of that popular extension with more precise shaping to follow the riders arm.
