The stainless steel shafts screw into orange 7075 aluminum heads, which are oval putting the material where it’s needed and not where it isn’t. The handles are a stainless steel/aluminum affair for a good balance of ergonomics and weight savings. The nuts have a nice matching o-ring and a thread friction element to keep them in place after the wheels are removed.
