Gain an aerodynamic advantage and unparalleled comfort with the Supersonic/Ergo+/SLC series aerobars, which offer industry-leading ergonomics, adjustability, and low weight.

The Supersonic/Ergo+ platform is designed to give riders the freedom to find their best possible position with a wide range of independent adjustments. With an impressive array of position options, these aerobars allow you to fine-tune your position for optimal performance.

The 50 SLC extensions feature a 50-degree ski-bend shape. These extensions also allow for a lateral offset of 7.5mm per side, enabling the rider to adjust the handle width without significantly altering the extension angle.

The SLC extensions offer the same range of ergonomic options as previous generations but with half the weight. This also allows for the installation of Di2 components inside the extension. All extensions have a diameter of 22.2mm in the clamp area and can be cut to size to fit nearly any rider. They also have a hole drilled for rearward cable routing.
