Sonic Ergo 39A Aerobars

The Sonic bracket provides a wide range of fit options, is lightweight, easy to adjust, and has a minimal frontal area. When combined with the Ergo armrest, it forms an aerobar that helps most riders optimize their position for both speed and comfort. The 39A is one of the latest versions in Profile Design's trusted aluminum extension series, offering reliability and performance for cyclists.

Using these aerobars is simple. First, adjust the Sonic bracket to fit your body and riding style. It's easy to make adjustments so you can find the most comfortable and aerodynamic position. Attach the Ergo armrest securely to the bracket. Once installed, rest your forearms on the armrests while riding. This will help you reduce wind resistance and improve your speed. When not in use, you can keep your bike in a dry place to prevent the aerobars from rusting. Clean them regularly with a soft cloth to maintain their appearance and performance. If you notice any loose parts, tighten them immediately to ensure safety.
