Profile Design Sonic Ergo T5+



The Sonic bracket has been designed as the successor to the J2, which has been a somewhat ignored part of our range. With this update it brings the 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 T5 extension features a 13° ski-bend designed to give a range of aerodynamic hand positions.
