The Chris King AreoSet 2:

headset now makes the proven Chris King quality available for 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 IS52 upper and lower cups, it is suitable for frames with a fully integrated 52 mm headset shell on the head tube 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.

Chris King quality:

Anyone who hears the name Chris King automatically thinks of extremely durable headsets. Manufactured by Chris King in Portland, Oregon, USA, to a standard of quality that rightly deserves the label ‘indestructible’. The benchmark in headsets – often copied, never equalled – which is why there is a 10-year warranty.

Chris King GripLock:

The multi-piece GripLock end cap features a slotted cone ring, which allows for an even easier connection between the steerer tube and head tube

IS, Integrated Standard fully integrated headsets:

Head sets with the Integrated Standard (IS) require frames that incorporate the raceway for the head set bearings; this is why they are also referred to as fully integrated. The head set then consists of the bearings, which are inserted into the head tube of the frame, the fork cone and the upper bearing cover with cap and claw.

Upper frame mount 1.5 inches / 52 mm diameter, bearing angle 45x45 degrees, upper steerer tube diameter 28.6 mm, 1 1/8 inches

Bearing installation dimensions IS 52-40 mm:

lower frame mount 1.5 inches / 52 mm diameter, bearing angle 36x45 degrees, lower steerer tube diameter 38 mm, 1.5 inches. The tapered seat is 40 mm.
