Profile Design 43 ASC Carbon Aerobar Extensions - 340mm Info
The Profile Design 43 ASC Carbon Aerobar Extensions are built around a specific ergonomic principle: a 43-degree grip angle that keeps your wrists in a neutral position, reducing fatigue and letting you hold your aero position longer without compromising form. Full carbon construction keeps them light and stiff, while CFD-optimized shaping works to reduce drag across the extension profile itself — not just the rider above it.
At 340mm, these extensions suit a wide range of riders and fit positions. The 22.2mm clamp diameter makes them compatible with the majority of standard aerobar systems, so they integrate cleanly into most tri and time trial setups without adapter hardware.
