Abstract
A bicycle fork includes a fork shaft configured to be rotatably borne by headset bearings in a head tube of a bicycle frame so as to rotate about a steering axis. The fork shaft includes a cylindrical fork shaft segment that is disposed eccentrically with respect to the steering axis. The cylindrical fork shaft segment is a right circular cylinder having a hollow interior, a cylindrical inner surface and a central longitudinal axis that lies within a symmetry plane of the bicycle frame and extends parallel to the steering axis. The central longitudinal axis of the cylindrical fork shaft segment is spaced apart from the steering axis in a direction of eccentricity that points in an opposite direction with respect to a forward direction of travel of the bicycle.
