The Profile Design Wing Ultimate S Base Bar is a full-carbon aerobar base bar with an integrated-stem concept. Built around aerodynamic integration, it is intended for riders seeking lower positions than standard aerobar designs can provide. The 420 mm center-to-center basebar has an effective stem length of 89.6 mm and an effective bar reach of 142.4 mm.
This Profile Design base bar provides extensive fit adjustment when assembled with compatible components. Armrest offset adjusts from -92.5 mm to -10 mm in 7.5 mm steps, while armrest width adjusts from 124 mm to 254 mm in 18.5 mm steps. Minimum armrest stack is 64 mm to 84 mm, allowing the setup to be refined for low and narrow riding positions.
Internal cable routing keeps the cockpit integrated, and the Wing Ultimate S is Di2 compatible. It fits a 1-1/8 in (28.6 mm) steerer tube and uses a 22.2 mm extension clamp diameter. The matte black carbon base bar weighs 390 g bare.
Configure the Wing Ultimate S with Profile Design carbon or aluminum aerobar extensions, ASC Pro extensions, A3A or A3C Riser Kits, A3 Reach Extenders, or an A3 Tilt Booster. Brackets, armrests, and extensions are sold separately; compatible tilt options include 0–15 degrees with the separately sold Aeria Ultimate Bracket or 18–30 degrees with the separately sold A3 Tilt Booster.
