A cable assembly comprises a housing defining a first cavity, a second cavity and at least one third cavity extending rearwardly from a front surface thereof, each third cavity communicated with the first cavity or the second cavity. The converters are formed with a group of inductors and at least two sets of buck and sync transistors that are arranged with the group so that conducted currents through each of the sets are directed through a respective one of the inductors and further directed to magnetically couple induced currents in the respective inductor of at least an associated one of the sets. The crash bar is of a tubular configuration constructed of steel and defines a C-shaped portion serving as a first foot support surface, while a top member provides a second foot support surface. The fairing can, on attachment, extend along a portion of the shaft from a location proximal the head of the club or implement.
