The Secure Lock mechanism prevents nipples from loosening, using a mechanical method instead of compounds or pastes. This allows for easy truing and tensioning of wheels post-build, without any special procedures. The Polyax design features a rounded head that acts like a ball joint, ensuring a better spoke-nipple alignment. Made from 7075-T6 aluminum with a special coating to reduce corrosion and friction, these nipples are 14g, 14mm long, and come in a pack of 100, all in red.
