ABSTRACT:
A bicycle steerer tube assembly having an oblong asymmetric cross section formed along a portion of the steerer tube. The asymmetric portion of the steerer tube has a first diameter that is generally aligned with an axis of rotation of the front wheel and a second diameter that is generally aligned with a plane of rotation of the front wheel. The first diameter is greater than the second diameter and provides lateral stiffness to the wheel assembly and the second diameter accommodates longitudinal impact absorption of the fork and wheel assembly.
