The Profile Design 52 ASC Carbon Aerobar Extensions are built around a specific problem in tri and time-trial positioning: most extensions compromise either comfort or aerodynamics, and these refuse to do either. Full carbon construction keeps weight down and rigidity up, while CFD-optimized shaping reduces drag without thinning the walls where it matters most.

The 52-degree grip angle is the defining feature here — it rotates your wrists into a more natural position under load, which you'll notice most on efforts beyond an hour. The grip length has been extended to accommodate shift button users who need extra real estate at the tip, and the extensions can be trimmed to your preferred length if you run shorter. Standard 22.2mm clamp compatibility means they drop straight into most existing aerobar setups without adapters.
