product Details

  • 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 Ergo armrest has been created to offer both a huge upgrade in our 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. This is the most adjustable clip on bar on the market (and in history).
