ENVE SES AR One-Piece Handlebar

The ENVE SES AR One-Piece Handlebar delivers great handling for performance road and all-road riders. Based on the SES AR Custom One-Piece Handlebar, it offers similar specs at nearly half the cost. The flared compound drops, at 5 cm per side, give better handling and stability on fast descents or rough roads. This barstem stays incredibly light with a 100 mm x 40 cm weighing just 360 grams. The SES AR also supports ENVE’s In-Route cable routing system, keeping your cockpit clean by hiding all cables internally. This barstem comes with ENVE’s new UL Carbon Computer Mount with wide computer and accessory compatibility. With its sleek design, smooth lines and featherweight build, the ENVE SES AR One-Piece Handlebar is a top choice for riders who want aerodynamic performance and comfort in a carbon cockpit.

 

Product Details

Key Features of the SES AR One-Piece Handlebar

  • Integrated One-Piece Design: Combines bar and stem for increased stiffness, lower weight and improved aero.
  • Carbon Construction: Made with ENVE’s proven carbon layup for race-ready stiffness and vibration damping.
  • Aero-Optimized Shape: Developed using CFD and wind tunnel testing to maximize speed while maintaining control and comfort.
  • Internal Cable Routing: This ENVE bar allows you to route your cables through the handlebar and into the frame for a clean look and improved aero.
  • Flared Drops: This barstem features a moderate 18 degree flare, giving more control for mixed surface riding.

Compatibility

This handlebar is only compatible with frames that use ENVE’s In-Route internal cable routing and it fits bikes with 1 1/8″ steerer tubes. This includes ENVE frames or frames with ENVE In-Route bearing covers. It works with internal cable routing and electronic disc brake groupsets, including Shimano Di2 systems. See Compatibility tab for more information.

Considerations

Because this is a one-piece handlebar, it offers less adjustment than a traditional bar-and-stem setup. Choosing the correct size is essential for achieving a proper fit.

Advice From Our Staff

The ENVE SES AR One-Piece Handlebar brings the flagship design of the SES AR Custom to more riders at a lower price point. Its compound flared drops deliver confident control on fast descents, while ENVE’s proven carbon layup provides comfort and vibration damping without giving up stiffness. Lightweight and aerodynamic, this all-round integrated barstem suits a wide range of riders who want performance, precision and a clean cockpit design.
