Profile Design - Sonic/Ergo/52a Aerobar Profile Design

Sonic Ergo 52A Profile Design extenders offer a wide range of settings, low weight and easy adjustment, as well as a minimal frontal area. Combined with the Ergo armrest, they create an aerobar that will help most cyclists optimize their position for speed and comfort. The Sonic Ergo is designed to have a 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 its minimalist appearance, the Sonic Ergo offers a full range of adjustments to meet exactly this objective.

52A extensions feature a 52° handle angle. The rider can choose to hold the handle high for a raised position, or low for a more open, head-up position. The length and rotation of the extension can be easily adjusted using the top bolt. There are 100 distinct positions possible simply by moving the armrests. Combined with the risers, this bar offers 1,500 possible configurations. As a clip-on bar, extension width and inclination can also be easily adjusted. This is the most adjustable clip-on bar on the market (and in history).
