Sonic Ergo 26a Aerobar

The Profile Design Sonic Ergo 26a Aerobar is a highly adjustable clip-on aerobar designed for triathlon and time trial riders who need to accurately dial in pad position, extension reach, and stack without compromising comfort. The independent adjustment range makes it easier to match a sustainable aero position to the rider’s flexibility, fit coordinates, and race goals.

1. 26° ski-bend extensions with defined hand height - 400mm-long, 22.2mm-diameter extensions use a 26a bend with 87mm rise and 7.5mm offset to support a stable wrist angle and secure grip in the aero position
2. Cut-to-fit extension length - Extensions can be trimmed to suit rider reach and shifter placement, helping achieve a cleaner, more repeatable position
3. Rear-exit cable routing ready - Extensions are drilled for rear-exit routing, supporting a tidy cockpit and straightforward cable management
4. Ergo armrests with 10mm pads - The Ergo armrest shape and included 10mm pads improve pressure distribution for longer efforts in the aerobars
5. Wide fit window for pad placement - Armrest width adjusts from 124mm to 290mm in 18.5mm steps (with extensions at 100mm), while armrest offset adjusts from -70mm to -17.5mm in 7.5mm steps for precise reach tuning
6. Stack adjustability for real-world fit - Armrest stack ranges from 60mm minimum (no riser kit) up to 130mm (with spacers), helping riders balance aerodynamics with sustainable breathing and shoulder comfort
