The Sonic / Ergo / 39a Aerobar is designed to help riders achieve an efficient, comfortable, and highly adjustable aerodynamic position. Built around the proven Sonic bracket system and paired with Ergo armrests, this setup offers a wide fit range, low weight, and straightforward adjustability — all while maintaining a minimal frontal profile.
Ideal for time trial and triathlon riders, the Sonic bracket allows precise tuning to optimise both speed and comfort. Combined with the updated A-Series 39a extensions, riders and fitters can fine-tune wrist angle without altering other critical fit dimensions.
