Headset bearings allow the fork steerer tube to rotate, enabling lateral movement of the front wheel and, therefore, changes in the bicycle’s direction. In this application, one of the most important details is the bearing edges, which can be straight (90º) or have variations on both edges (e.g., 36º/45º).
This specification is essential when selecting the correct bearing for the bicycle, as different angle variations can occur for the same dimensions.
