Profile Design Sonic Ergo 50a Clip On Aerobar

The Sonic/Ergo is designed to present a 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 Sonic bracket has been designed as a successor to the J2. With this update it brings Profile Design’s new 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. There are 100 distinct position options achievable just by moving the armrests. Combine that with the risers and this bar offers 1500 possible configurations. As a clip on bar it is also possible to adjust the extension width and tilt easily.

The 50a extensions come with a 50° ski bend shape. They offer a 7.5mm lateral shift per side. This allows the rider to get their hands narrower or wider without tilting the extensions so much that they touch the shifters. The extension length and rotation can be easily adjusted using the top bolt. The extensions are 400mm long and cables can be routed from the front to the rear.
