ASC stands for Aero Shaped Carbon: Profile Design uses carbon's ability to be moulded into an aero form while keeping strength and stiffness. The 43° grip angle gives a neutral wrist position so you can relax, and the shape was optimised with CFD to reduce drag.

Highlights

  • 43° grip angle for a neutral wrist
  • CFD-optimised aero shape without sacrificing strength
  • Wrist area shaped to smooth airflow over the arm and add contact area
  • Electronic or mechanical shifter compatible
  • 232 g pair (400 mm)

Who it's for

The 43 ASC is intended to improve the aerodynamics of your existing bars, and Profile Design says it pairs well with the Race+ or Ergo+ armrest. For a computer mount, pair it with the ASC Computer Mount (sold separately).

Compatibility & fit

22.2 mm outer diameter (18.8 mm inner), so the extensions fit any aerobar designed for 22.2 mm extensions. The 400 mm extension can be cut down to a minimum of 290 mm, measured from the front of the clamp. Sold as a pair (one left, one right). Follow Profile Design's 43 ASC Extensions Installation Instructions.

Aerobar fitting and position set-up is a separate workshop service and isn't included in the price. Our workshop can fit it and set up your position.
