Profile Design 52 ASC Extensions

The 52-degree angle is designed to place your wrists in a more neutral, ergonomic position. This reduces strain during long rides while providing better control and comfort compared to flatter extension designs.

Yes, the grip section is specifically extended to accommodate electronic shifters. If you find the length excessive for your setup, the carbon material can be trimmed to achieve a custom fit.

These extensions feature a standard 22.2mm mounting area, making them compatible with the vast majority of standard aerobar clamps on the market.

The choice depends on your reach and preferred arm position. The 340mm option is generally better for riders seeking a more compact setup, while the 400mm version offers more room to adjust your hand position for comfort or to accommodate specific shifting hardware.

The carbon fiber construction allows for complex, aerodynamic shaping that would be difficult to achieve with metal. It provides a high strength-to-weight ratio, ensuring the extensions remain rigid under pressure while keeping the front end of your bike light.
