PROFILE DESIGN Sonic Ergo 4525a Extender

Sonic Ergo 4525a extension

The new Sonic Stand was designed as the successor to the J2. With this update, it brings the next-gen fit range to a wider price range, replacing the J2 mount. The Ergo armrest was created to provide both a huge improvement in the range of adjustment as well as increased rider comfort.
