Abstract: A sports shaft having an elongated body having a perimeter defined by a plurality of main walls with adjacent ones of the main walls being interconnected through a corresponding one of a plurality of edge walls, the edge walls being spaced apart around the perimeter. A respective bumper extends along at least part of length of at least one of the edge walls. The main and edge walls without the respective bumper have a first stiffness along a longitudinal direction of the shaft, and a combination of the respective bumper with the at least one of the edge walls has a stiffness along the longitudinal direction greater than the first stiffness. A method of making a sports shaft is also discussed.
