Our new 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 our 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.
 
Performance
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.
 
Fit Data
Armrest Offset: -70mm to -2.5mm in 7.5mm steps
Armrest Width: 124mm to 290mm in 18.5mm steps (With Extensions at 100mm)
Armrest Stack: 60mm (no riser kit) to 130mm in 5mm increments (With aftermarket Riser Kit)
The extension length and rotation can be easily adjusted using the top bolt.
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. This is the most adjustable clip-on bar on the market (and in history).
