The spindle ends are arranged in a circular array with the spindles rotatable about their longitudinal axes. The screw fasteners are configured for screw engagement with screw fasteners of another type mounted on a wheel attachment member to/from which a wheel can be attached/detached. An adjustment mechanism collectively changes positions of the spindle axes between a circular array with a first radius and a circular array with a second radius.",
