The ZS headset is pressed into the head tube at the top; the press-fit dimension in the frame is 49 mm at the top and the fork steerer tube diameter is 1 1/8 inch / 28.6 mm at the top.

EC49/40 bottom insertion dimension:

The EC headset is pressed into the head tube at the bottom; the press-fit dimension in the frame is 49 mm and the fork steerer tube diameter 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 an exact match for the bearing cups. Zero Stack refers to the minimal protrusion of the bearing cups from the head tube, whilst ZS44, for example, denotes the installation dimension, the outer diameter of the bearing cup and the inner diameter of the bearing cups within 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’ refers to the installation dimension, the outer diameter of the bearing cup and the inner diameter of the bearing cups in the frame. The headsets must be fitted using a special tool; the frame simply needs to be cleanly pre-milled.
