Chris King quality:

Anyone who hears the name Chris King immediately thinks of extremely durable headsets. They have been produced by Chris King in Portland, Oregon, USA for 14 years, and to a standard of quality that rightly deserves the label ‘indestructible’. The benchmark when it comes to headsets – often copied, never equalled – which is why there is also a 10-year warranty.

Chris King GripLock:

The NoThreadSet headset with the newly developed GripLock cap. The multi-piece cap features a slotted cone ring, which allows for an even easier connection between the steerer tube and the head tube.

ZS44/28.6 top thread diameter:

The ZS44 headset is pressed into the top of the head tube; the press-fit dimension in the frame is 44 mm at the top and the steerer tube diameter is 1 1/8 inch / 28.6 mm at the top.

EC49/40 bottom installation dimension:

The EC44 headset is pressed into the head tube at the bottom; the press-fit dimension in the frame is 44 mm and the fork steerer tube opening is 1.5 inches at the bottom. The headset cone requires a 40 mm seat on the fork.

ZS/Zero Stack – semi-integrated headset:

Headset sets designated ZS / Zero Stack are also referred to as semi-integrated headsets. They require a frame designed for this purpose with exactly the same mounting for the bearing cups. Zero Stack refers to the minimal protrusion of the bearing cups from the head tube, whilst ZS44, for example, refers to the installation dimension, the outer diameter of the bearing cup and the inner diameter of the bearing cups in the frame. These headsets can usually be fitted without special tools; the frame simply needs to be cleanly pre-milled.

EC/External Cup – external headset:

Headset assemblies designated EC / External Cup are also referred to as external or classic headsets. These headsets require a frame designed for this purpose with an exact fit for the bearing cups. ‘External Cup’ refers to the relatively large projection of the bearing cups on the head tube, whilst, for example, ‘EC44’ denotes the installation dimension, the outer diameter of the bearing cup and the inner diameter of the bearing cups within the frame. The headsets must be fitted using a special tool; the frame simply needs to be cleanly pre-milled.
