Profile Design 52a Aerobar Extensions | 400 mm

The new 52a series aerodynamic aero bar extensions are a refined and more ergonomic evolution of the popular T-series. Designed to allow every cyclist to find their optimal hand position, the 52° angle—encoded in the name—offers the flexibility to choose between a higher, more aggressive aero posture or a lower, more open position for greater comfort.

Key Features:

• Comfortable and Versatile Design: The 52° angle allows easy adjustment between a “shrugged” or “head-up” arm position, maximizing comfort and aerodynamic efficiency.
• Width Adjustability: The 52a extensions offer 7.5 mm lateral adjustment on each side, enabling fine-tuning of arm spacing without compromising shifter positioning.
• Aerodynamic Performance: The rise section features a Kamm tail profile, which reduces drag and improves the bike’s overall aerodynamic performance.
• Universal Compatibility: With a 22.2 mm diameter, these extensions are compatible with nearly all aero cockpit setups, and rear-exit cable routing ensures a clean, streamlined appearance.
• Ergonomic End Caps: Specially shaped end caps enhance hand comfort during long-distance rides.
