Sonic/Ergo/26a AerobarThe Sonic Ergo is designed to present minimal frontal area to create as little aerodynamic drag as possible.

Combining this with the Ergo armrest creates an aerobar that will aid most riders in optimizing their position for both speed and comfort. The extension length and rotation can be easily adjusted using the top bolt. There are 100 distinct position options
