Aerodynamics. Integration. Performance.

The Black Inc AB03 redefines cockpit design for triathletes and time trial athletes, offering wind tunnel-tested aerodynamics, 
ergonomic precision, and fully integrated aero extensions—engineered to help you conquer every course, from Ironman to UCI-level TT.

One of the biggest challenges for triathletes and time trialists has always been cockpit integration. Traditional barsetups often force athletes to choose between aerodynamics, comfort, or adjustability—a compromise that can cost precious seconds.

The Black Inc AB03 Integrated Carbon Barstem eliminates those limitations. With its removable, direct-mount aero extensions and design inspired by Factor’s cutting-edge race machines, the AB03 gives athletes the ultimate advantage: a cockpit that adapts to race-day needs without sacrificing speed or stability.

Key Features

Aero Efficiency Redefined

The AB03 allows triathletes to hold the most effective position possible—whether that’s all-out aero for a time trial or a balance of comfort and efficiency for an Ironman. The extensions, developed for the Hanzo TT bike, channel airflow smoothly around the forearms for maximum speed.

Integrated Carbon Construction

The one-piece carbon barstem reduces drag, eliminates unnecessary junctions, and creates a cockpit that is both lightweight and ultra-stiff, ensuring direct power transfer in every pedal stroke.

Refined Ergonomics for Endurance

  • Extensions cuttable at either end for a custom fit.
  • Tops with a 3° sweep for natural wrist angles.
  • Chamfered corners for sprinting clearance.
  • Drops with a 7° flare—adding 29mm width for confident handling.
  • Adjusted drop-to-lever reach to account for modern Shimano/SRAM levers.

Versatility Without Compromise

  • With extensions: a triathlon and TT-ready cockpit for maximum aero advantage.
  • Without extensions: a super-fast, ergonomic barstem for training rides.
  • Fully internal routing (electronic + disc brakes only) ensures a clean setup.
  • Integrated GoPro-style mount provides ideal positioning for computers, lights, or action cameras.
