The Chris King AreoSet 3:

This headset now brings the proven Chris King quality to road bikes with internal cable routing from ENVE or FSA. Brake and gear cables, as well as DI2 cables, are discreetly routed through the frame, resulting in a clean and aerodynamic cockpit. With EC44 upper and lower cups, the headset is suitable for frames with a 44 mm head tube internal diameter and tapered forks with a steerer tube diameter of 1 1/8 inch / 28.6 mm at the top, 1.5 inches / 38 mm at the bottom and a 40 mm taper. The cap covers are made from aluminium and CNC-machined; the bearings are made from stainless steel with multiple seals and are so well-made that Chris King offers a 10-year warranty on all headsets. Furthermore, the bearings are easy to maintain.

FSA Aerodynamic Cable Routing:

Hidden cables and lines are essential when it comes to modern bicycles and aerodynamic advantages in competition. As a complete system, the Aerodynamic Cable Routing System, or ACR for short, offers a wide range of stem, handlebar, headset and fork combinations to provide the right fit for every frame material and rider size. It routes all shift and brake cables through the stem. From there, the front brake cable passes through the steerer tube into the left fork leg. The rest flows around the steerer tube into the down tube. These features make ACR a complete solution for cable integration.

ACR works by routing brake hoses and cables through the handlebars, into the stem and down into the front section of the head tube. This is achieved by using a fork with a round 1.125-inch steerer tube and routing the hoses/cables between the steerer tube and the larger 1.5-inch upper bearing of the headset. The upper bearing cap and spacers match the shape of ACR-compatible FSA stems.
