FSA Headset - No. 94 | HBS - ZS56/28.6 | ZS56/40

Semi-integrated "ZeroStack" headset for "tapered" forks with a 1 1/8 to 1.5 inch steerer tube and an outer head tube diameter of 62 mm. Equipped with angular contact ball bearings (36° / 45° ACB) and an aluminum HBS top cover (Headset Blocking System) with 150° rotation range and steering stop.

Stack height: 20.5 mm + 6 mm = 26.5 mm

Ahead headsets can be divided into 3 types: "classic", semi-integrated ("Press Fit") and fully integrated ("Drop In"). While the bearings are located outside the head tube in the "classic" design, they are located inside the head tube in "Press Fit" and "Drop In" headsets, which enables a lower overall height. In contrast to "Press Fit" headsets, "Drop In" models do not need to be pressed in. The running surfaces are already incorporated into the head tube, with an angle of 36° or 45°.
