HED PRO-LOCK ALLOY NIPPLE~BLACK~14MM / HED PRO-LOCK NIPPLE~BLACK~14MM

Pro Lock Technology: A patented two-component adhesive is pre-applied to the spoke nipple threads. When rotated during assembly, the adhesive is activated and fully hardens within 6-7 hours, preventing spokes from loosening under severe vibration or heavy loads.
N-Tall Design: Specifically developed for high-end rims requiring hidden or deep-seated spoke nipples. The longer body extends into the inner rim layer, providing more stable support and better tool engagement.
Spherical Contact Surface (Pro Head): Features a spherical contact base that allows the spoke nipple to automatically fine-tune its angle within the rim hole (self-aligning), reducing spoke bending stress and distributing forces more evenly.
Durable Materials: Typically made of brass and nickel-plated, offering excellent corrosion resistance, making them ideal for long-term use in harsh climates or high-humidity environments.
