Profile Design Sonic Ergo 52a Aerobar Handlebar

The Profile Design Sonic Ergo 52a Aerobar Handlebar is engineered to deliver both speed and comfort. Its Sonic bracket minimizes frontal area to reduce aerodynamic drag, while offering an extensive fit range and low weight for a performance-focused riding position.

Optimized 52° Grip Angle for Multiple Positions: The 52a extensions feature a 52-degree grip, allowing riders to choose between a high, shrugged position for aerodynamics or a lower, more open position for endurance. This flexibility makes it suitable for both aggressive time trial setups and long-distance comfort.

Limitless Fit Configurations: With 100 armrest positions and the ability to adjust extension length, rotation, width and tilt, the Sonic Ergo offers up to 1,500 possible configurations when combined with risers. This makes it the most adjustable clip-on aerobar in history, giving every rider the ability to find their perfect fit.

Lightweight Yet Highly Functional Design: By simplifying the extension clamp and shifting the wing forward to the bar centerline, Profile Design created their lightest bracket without compromising stability or versatility. The Ergo armrests feature a flippable design, allowing precise micro-adjustments to match previous setups or fine-tune comfort.

With its reliable aluminum extensions and proven ergonomic armrest design, it’s a high-performance upgrade for triathletes and time trialists seeking speed, efficiency and personalized fit.
