The new Sonic bracket has been designed as the successor to the J2, which has been a somewhat ignored part of the range. With this update it brings a new generation fit range to a wider range of price points, replacing the J2 bracket. 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.
The Sonic/Ergo is designed to present minimal frontal area to create as little 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.
The Profile Design Sonic Ergo 43a Aerobar offers a neutral wrist position with the forearms lying along the extensions for greater aerodynamic benefit. A wide range of adjustment is possible to allow a powerful and wind-cheating position to be dialled in with both the width and the offset able to be altered.
