Sapim Secure Lock Alloy and Brass Nipples.
- Secure Lock prevents nipples from loosening via a mechanical means instead of a thread locking compound or paste
- Allows for truing and tensioning of wheel after wheel builds without any special procedures
- Polyax design features a round shape of the head that works like a ball-joint between the rim and nipple ensuring a better spoke/nipple line
- Aluminum: 7075-T6 aluminum, special coating on thread and nipple surface to further reduce corrosion and reduce friction between spoke/nipple and nipple/rim
