As the successor to the J2 a somewhat overlooked product, the new Sonic bracket update brings the new generation fit range to a wider range of price points.

The Ergo armrest has been created to offer both a huge upgrade in fit range as well as increased rider comfort with a supportive curve to cup the arms. Designed to present minimal frontal area to eliminate as much of the aerodynamic drag as possible, the main purpose of an aerobar is, of course, to get the rider into a fast position despite a fairly minimalist appearance the Sonic/Ergo offers a comprehensive fit range for exactly this purpose.
