Profile Design 43A Aerobar Extensions 400mm

The new range of extensions have evolved from the well proven T-Series. They have been designed to offer distinct fit options. Profile Design 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
The 43a has been designed to offer great ergonomics and cost effective aerodynamic enhancement. Along with the optimized angles it has a 7.5mm per side lateral offset to the grip to allow more options for hand position.

Orgin
Profile Design had great success with the T3 extension from the previous range of bars. The 43a is an enhanced version of that popular extension with more precise shaping to follow the riders arm.

Who is it for?
The extensions will fit in any aerobar that is designed for 22.2mm. The 43a extension is a great option for any rider looking for a neutralwrist angle and positioning versatility.
