What Our Gearhead(R) Experts Are Saying:"This is a great option for riders who want serious adjustability without a bulky setup. The Sonic bracket keeps the front end clean and light, and pairing it with the Ergo armrest makes long aero efforts more comfortable. I like that you can choose between 26deg, 39deg, or 52deg extensions depending on your preferred hand height."When we're chasing speed against the clock, we want an aerobar that disappears into the wind while keeping us comfortable for the long haul. The Sonic Ergo Aerobar from Profile Design blends a low-profile Sonic bracket with the supportive Ergo armrest to create a system built for both aerodynamic efficiency and adaptable fit. Designed with minimal frontal area in mind, the Sonic bracket helps reduce drag while offering an extensive adjustment range to refine stack, reach, and armrest position. Paired with the smoothly curved Ergo armrests, it supports stable elbow placement for sustained power output. Riders can choose between 26A, 39A, or 52A aluminum extensions, each offering a distinct grip angle-26deg for a lower hand position, 39deg for a balanced shrugged posture, or 52deg for a higher, more closed aerodynamic stance. This range allows athletes to dial in wrist angle and upper-body posture for optimal speed and comfort across triathlon and time trial efforts.
