Wolf Tooth Premium Headset

Wolf Tooth Premium ZS56 bottom bracket for frames with a 56 mm press-fit diameter at the bottom of the head tube and forks with a 1.5-inch / 40 mm steerer tube diameter at the bottom.

Wolf Tooth headsets are manufactured in the USA from 6061 aircraft-grade aluminium and are available in two series, Premium and Performance, which differ in terms of bearing materials.

Wolf Tooth Premium bearings:

The Premium series, featuring stainless steel bearings, is designed for maximum durability and smooth operation. Multiple layers of specially shaped double-lip seals protect the bearings even under the most adverse conditions. This makes them lightweight, strong and extremely durable.

ZS56 Zero Stack bottom thread:

The ZS56 headset is pressed into the head tube from below. The press-fit dimension in the frame is 56 mm and the fork steerer tube diameter is 1.5 inches / 40 mm 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, refers to the installation dimension, the outer diameter of the bearing cup and the inner diameter of the bearing cups within the frame. The headsets can usually be fitted without special tools; the frame simply needs to be cleanly pre-milled.

Wolf Tooth Premium Headset Specifications:
