Profile Design Sonic Ergo 39a Aerobar Handlebar

₹15,990

Precision Aerobar Setup for Speed & Comfort

Description

The Profile Design Sonic Ergo 39A Aerobar Handlebar is built to help riders achieve a faster and more efficient position without sacrificing comfort. By combining the streamlined Sonic bracket with the supportive Ergo armrest, it creates a setup that enhances both aerodynamics and ride stability.

Minimal Drag, Maximum Performance: The Sonic/Ergo system is engineered to minimize frontal area, reducing aerodynamic drag and helping you maintain higher speeds with less effort. Despite its clean, minimalist look, it offers an impressive fit range that lets riders dial in the ideal aerodynamic posture for their style and goals.

Customizable Positioning for Every Rider: The 39A extensions feature a 39° grip angle that allows both high hand positions for a compact, shrugged profile or lower hand positions for a more open, head-up posture. Extension length and rotation can be quickly adjusted, giving you complete control over fine-tuning your reach and handling.

Unmatched Adjustability in a Clip-On Aerobar: With 100 armrest positions and up to 1500 possible configurations when paired with risers, these aerobars offer more adjustability than any clip-on bar ever made. You can easily modify tilt, width, height and extension placement, ensuring a perfectly tailored fit whether you're racing, training, or adapting from a previous setup.

Lightweight, Smartly Engineered Construction: Developed after the introduction of the Supersonic (J5) bracket, the Sonic bracket simplifies the clamp design and shifts the wing forward for better balance and reduced weight. As the lightest bracket in the lineup, it offers impressive strength and stability while keeping your cockpit lean and responsive.

The Ergo armrests feature a flippable design that allows subtle adjustments by swapping sides or rotating their orientation. This helps you achieve micro-level fit refinement or perfectly match the position from your earlier aerobar or bike setup, making transitions smoother and more accurate.

Features
  • Streamlined Sonic Bracket: Minimizes frontal area for reduced drag while keeping the cockpit stable and responsive during high-speed efforts.
  • Adjustable 39A Extensions: 39° bend allows high or low hand positions with quick tuning of reach, rotation and control to match your riding style.
  • Wide Fit Customization: Offers up to 1500 setup combinations with adjustable tilt, width, stack and extension placement for a tailored aero fit.
  • Lightweight Construction: 6061-T6 aluminum structure with a forward-shifted wing delivers strength, reduced weight and balanced handling.
  • Ergo Armrest Design: Flippable cups allow micro-adjustments in orientation and spacing to recreate past positions or refine comfort precisely.

Technologies

  • Sonic Bracket System: A simplified lightweight clamp with a forward wing that improves balance, reduces drag and increases cockpit stiffness.
  • Ergo Armrest Interface: Multiple mounting options with rotational adjustability enable more precise fine-tuning than standard clip-ons.
  • 39A Extension Geometry: A 39° angle supports aerodynamic hand placement while maintaining stable control across varied rider positions.
