Performance the Sonic/Ergo is designed to present minimal frontal area to create as little aerodynamic drag as possible. The main purpose of an aero bar 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 armrest stack: 60mm to 70mm in 5mm increments. 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). it is worth noting that our previous top level clip on aero bar, the J4/F35, OFFERED 90 possible configurations. This s the significant step forward we've made with our new generation aero bars in allowing riders to precisely adjust their position.
