Abstract:
1. A spacer for increasing a width of a rotatable performance device supported by a tether, the rotatable performance device being operable with and without the spacer, and including an axle, a bearing member, a first outer lobe, and second outer lobe each supported by the axle, the first outer lobe and the second outer lobe each having an outer lobe recess, the spacer comprising: a first face including a recess having a first cross-sectional size, the recess being configured to receive the bearing member; a second face opposite the first face and including a projection having a second cross-sectional size, the second cross-sectional size being equal to the first cross-sectional size within a clearance fitting range, and the projection being configured to be removably received in the outer lobe recess of the first outer lobe; and an angled surface disposed between the first face and the second face, the angled surface facing a direction that forms an acute angle with a width direction between the first face and the second face, the angled surface thereby being configured to direct the tether away from the second face, wherein the spacer is configured such that when the spacer is installed the rotatable performance device defines a first longitudinal axial length, and when the spacer is removed the rotable performance device defines a second longitudinal axial length shorter than the first longitudinal axial length.
