About Sonic Ergo 4525A

The Sonic Ergo Aerobar 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 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 aero bar on the market (and in history).

Some call it TT Bar, or Triathlon Aero Bars, or Tri Bars. Same product, different names! Be less confused, be more confident.
