Description

Unlock ultimate speed and sustained comfort with the Profile Design Sonic/Ergo/39a Aerobar, the benchmark for performance-driven cyclists and triathletes. Engineered for the dedicated competitor looking to gain a crucial advantage, this aerobar system is your key to unlocking a faster, more sustainable, and powerful riding position. Experience a significant reduction in frontal area, allowing you to slice through the wind with greater efficiency. This translates directly into higher speeds for the same effort, helping you crush your goals on race day. The advanced ergonomic design focuses on rider comfort, ensuring you can maintain your optimal aero tuck for longer durations without sacrificing power or succumbing to fatigue on long-course events.
The foundation of this class-leading system is the Sonic bracket, renowned for its minimal frontal profile and extensive range of adjustability. Paired with the highly acclaimed Ergo armrest, this combination provides a supportive and comfortable platform. The armrest is designed to cup the arms securely, improving control and reducing pressure points, which is critical for maintaining stability and focus during intense efforts. This meticulous attention to fit and feel allows for a seamless integration between rider and machine, creating a unified aerodynamic silhouette.
Extensions
The defining feature of this setup is the 39a extensions. These extensions feature an aggressive 39° bend, promoting a streamlined ´high-hands´ position favored by elite athletes. This specific angle is meticulously designed to optimize wrist comfort while enhancing aerodynamic flow over the arms and body. The unique shaping allows for a smooth transition from the grip to the extension, providing a secure and natural hand position for maximum control and power transfer. The A-Series design allows riders and professional bike fitters to precisely fine-tune the wrist angle without altering other critical aspects of the bike fit, ensuring your position is perfectly dialed-in.
