The Profile Design 52 ASA Aluminium Extensions are designed around modern high-hand aerobar positioning, featuring a 52° grip angle combined with a shaped design that follows the natural position of the arms. By incorporating a lateral offset into the extension itself, the 52 ASA creates a more natural arm and hand alignment while maintaining compatibility with standard 22.2 mm aerobar systems.
This shaped design helps riders achieve a narrow and supported position without requiring excessive extension rotation, improving comfort and creating a cleaner front-end setup. The higher hand position can also assist riders in achieving a more relaxed and aerodynamic posture during longer efforts.
Constructed from aluminium using an advanced forming process, the 52 ASA delivers the fit benefits of shaped extensions in a durable and cost-effective package. Ergonomic end caps further improve comfort at the hand contact point during training and racing.
Compatible with any aerobar system designed around a standard 22.2 mm clamp diameter.
Ideal for: riders seeking a modern high-hand position with improved arm alignment, support and long-distance comfort.
Bike Fit Note: Extension shape can significantly influence comfort, shoulder posture and aerodynamic sustainability. Different hand angles and shapes suit different riders, with recommendations included as part of my bike fitting process.
