Bicycle fork shank with a variable stiffness

摘要

A bicycle fork shaft is designed in such a way that it is mounted in a driving plane of the bicycle. A thickness varies at a point on the wall of the fork shaft body in a lower region of this as a function of the cross section angle of the point to the plane of travel, wherein the wall thickness at a maximum in the plane of travel is. An inner wall of the lower section, can be elliptical, wherein a minor axis is aligned to the plane of travel and a main axis is orthogonal to the driving plane.
