a stem clamp region;

a plurality of control end regions; and

a plurality of transition regions, wherein a cross-section of at least a portion of one or more of said plurality of transition regions is asymmetric based on an intersection of four ellipses and defined by four different radii and an axis of symmetry of said ellipses, wherein said four ellipses have a coincident center, wherein said axis of symmetry of said ellipses is offset by an angle (α) from a fore-aft plane of said handlebar, wherein said four ellipses are symmetrical across said axis of symmetry of said ellipses.
