The Sapim Polyax Nipple 13G is designed to provide optimal spoke alignment and even tension distribution. Its unique Polyax head acts like a ball joint between the rim and nipple, ensuring a straighter line between spoke and nipple for improved wheel strength and longevity.

Available in brass or aluminum, these nipples offer a balance of strength, corrosion resistance, and precision. The 13-gauge size (2.3 mm) makes them ideal for heavy-duty wheels, e-bikes, and cargo setups that demand maximum durability.
