Sonic Ergo+ 52 ASA Aerobar

Profile Design Sonic Ergo+ 52 ASA Aerobar is a clip-on aerobar built for triathlon and time trial riders who want a higher-hand position and a more natural wrist/forearm alignment than traditional straight extensions. The sideways (ASA) extension orientation and 52° grip angle support a comfortable, stacked riding posture for staying aero over long efforts, while the Sonic bracket and Ergo armrests provide a wide fit window for precise setup on a variety of base bars.

Dial-in fit for a high-hand aero position

1. ASA sideways extension orientation - Aligns the extensions with the arm’s natural position for a more ergonomic grip and forearm support
2. 52° grip angle - Delivers a higher hand position than traditional aerobars to help riders hold an aero posture with less strain
3. Top-bolt extension adjustment - Fine-tune extension length and rotation without fighting a complicated clamp interface
4. Ergo armrests with 10mm pads - Broad, supportive contact area designed for stability and comfort during sustained aero riding
5. Wide armrest positioning range - Width adjusts from 124mm to 290mm (18.5mm steps, with extensions at 100mm); offset adjusts from -70mm to -17.5mm (7.5mm steps)
6. Stack options for modern fit - Minimum armrest stack is 60mm (no riser kit); adjustable up to 130mm in 5mm increments with an aftermarket riser kit (not included)
