SAPIM Aluminum Polyax Secure Lock Nipple 14G - 14mm

SAPIM Aluminum Polyax Secure Lock nipples offer a perfect balance of low weight and resistance to loosening.

Aluminum nipples are an effective choice when you want to reduce the weight of the wheel's outer circumference. Especially for road, gravel, and racing wheels, or when paired with lightweight rims, these subtle weight differences have a significant impact on the overall feel of the wheel.

The Polyax shape features a nearly spherical nipple head, allowing it to naturally follow the angle of the spoke and optimize the contact surface with the rim hole. Even in structures where spoke lines are prone to stress—such as deep-section rims, offset rims, or disc brake wheels—this design properly compensates for angle discrepancies, reducing spoke twist and uneven tension, and ensuring durability even in lightweight wheels.

Furthermore, the Secure Lock specification uses precision thread machining to increase rotational resistance, powerfully suppressing loosening caused by vibrations during riding. These are the nipples to choose when you want to build a lightweight wheel but are concerned about relying on weight reduction alone.

Note, however, that aluminum nipples require greater precision during assembly than brass nipples. They deliver their full potential when used by professionals who account for high-tension assembly, anti-seize measures, proper tool selection, and condition checks during readjustments.

Light, beautiful, and built right. These are the nipples designed for that purpose.
