The Profile Design Wing Ultimate S Base Bar with A3 Bracket is a full-carbon integrated aerobar base bar built for aerodynamic integration and a broad range of fit adjustment. Its 420 mm center-to-center base bar width, 89.6 mm effective stem length, and 142.4 mm effective bar reach create a defined integrated cockpit platform. The bare base bar weighs 390 g and is finished in matte black.
The included A3 bracket kit allows independent adjustment of cockpit components for detailed position tuning. Armrest offset adjusts from -92.5 mm to -10 mm in 7.5 mm steps, while armrest width spans 124 mm to 254 mm in 18.5 mm steps. Minimum armrest stack ranges from 64 mm to 84 mm, and bracket tilt is adjustable from 0° to 30°.
This Profile Design aerobar base bar is intended for riders pursuing lower positions than standard aerobar designs, without being limited to a single arm pad height. The A3 bracket adds 30 mm of reach and 15° of additional tilt flexibility. It is natively compatible with A3 risers and works with A2 risers when used with an adaptor.
Internal cable routing supports a clean integrated setup, and the bar is Di2 compatible. The 22.2 mm extension clamp accepts Profile Design carbon or aluminum aerobar extensions, including ASC Pro extensions. Armrests and extensions are not included, allowing the cockpit to be completed with the preferred compatible components.
