Product Details
Profile Design 43SLC Aerobar Extensions 400mm
The Super Light Carbon (SLC) series brings the low weight of the 35C+ to our standard carbon extensions saving an average of 100g.
Improvements in manufacturing allow us to upgrade our carbon extensions for lower weight and the ability to fit Di2 parts inside using the Aeroport. The dimensions are the same as the previous generation 35, 50 and 4525, with the addition of the 43SLC to complete the range.
43SLC
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.
Tech Guide
- Clamp Diameter 22.2mm

The SLC series offers a great range of size options and class leading low weight while still meeting our stringent testing standards.
