American Classic SPOKES NIPPLES

Standard Aluminum spoke nipples have a deserved reputation of breaking due to fatigue after about one year. Bill Shook identified the cause of this problem and designed the AC aluminum nipples to be work horses. Bill likes aluminum as a material for spoke nipples because it is six times lighter than brass thus reducing rotational weight. The threads in the head of the AC nipple are loaded in compression. The body of the AC nipple is not loaded in tension. There is no stress concentration of loads at the junction of the AC nipple head and body, which is the place where the competitor’s nipples fatigue and eventually break. As a rider, the AC spoke nipples mean better durability for your wheels and increased performance from the reduced rotational weight at the rim, the place it counts most.
