Profile Design 52 ASC Carbon Aerobar Extensions

The Profile Design 52 ASC Carbon Extensions are premium aerodynamic extensions designed to improve comfort, control, and efficiency for triathlon and time-trial riders. Constructed from lightweight carbon, the extensions feature a 52-degree grip angle that provides increased wrist support and a comfortable hand position. The aerodynamic shape is designed using CFD to reduce drag while maintaining strength and rigidity. A 16mm total offset positions the extensions naturally alongside the rider's arms, while the standard 22.2mm mounting diameter ensures compatibility with most aerobar brackets. Available in 340mm and 400mm lengths, the extensions can also be trimmed to suit individual fit requirements. They support both electronic and mechanical shifters and are supplied as a pair.
