The G-Sport Taper Hex Nipples are another incredibly detailed and extremely important touch of greatness from G-Sport. Most people don't think about the little nipples that hold their spokes to the rims, but G-sport George isn't most people. Ordinary aluminium nipples have a bad reputation for rounding off, but G-sports patented Taper-Hex Nipple shape makes it work better than brass. The tapered hexagon shape means that the key can easily slide down the nipple to fit perfectly and transmit maximum torque without deforming.
