Description
APIM Aluminum Polyax Secure Lock is an aluminum nipple that combines light weight with resistance to loosening.
Aluminum nipples are an effective choice when you want to reduce the weight of the outer circumference of the wheel. Especially for road, gravel, and race wheels, and in combination with lightweight rims, even small weight differences can significantly impact the overall feel of the wheel.
The Polyax shape is designed to optimize the contact surface with the rim hole by giving the nipple head a near-spherical shape, allowing it to naturally follow the spoke angle. Even in structures where spoke alignment can be difficult, such as deep rims, offset rims, and disc brake wheels, properly accommodating angle differences reduces spoke twist and tension unevenness, ensuring durability even with lightweight wheels.
Furthermore, the Secure Lock specification significantly increases rotational resistance through microscopic processing of the screw threads, powerfully suppressing loosening due to vibrations during riding. If you want to build lightweight wheels but are concerned that being merely lightweight isn't enough, this is the nipple to choose.
However, aluminum nipples require higher precision during assembly compared to brass nipples. Their full benefits are realized when used with professional assembly in mind, including high-tension installation, anti-seizing measures, proper tool selection, and condition checks during re-adjustment.
Light, beautiful, and properly assembled. This nipple is for that purpose.
