Product Information
Full details
This guide is for wheel builders and cyclists who prioritize wheel reliability and durability, especially under demanding conditions. The key benefit is enhanced spoke security and longevity, preventing loosening even with hard use. A potential consideration is that while tension can be readjusted, the Loctite treatment makes initial tensioning and potential future adjustments slightly different from standard nipples. These nipples offer exceptional fit and strength, featuring a black electroplated finish for increased surface hardness and are constructed from brass for long life.

FAQs
What is the purpose of the Loctite Threadlock on these nipples?
The Loctite Threadlock prevents spokes from loosening due to vibration and stress, enhancing the overall durability and reliability of the wheel.
Can I still true or tension a wheel built with these nipples?
Yes, the Prolock treatment is designed to allow for future tension adjustments, though it offers more initial security than standard nipples.
What size spokes are these nipples compatible with?
These nipples are designed for 2 mm diameter spokes.
Why are they 14mm long?
The 14mm length is optimized to work well with modern, thicker rim designs, providing sufficient engagement.
Are these nipples suitable for all types of cycling?
They are particularly beneficial for demanding disciplines like mountain biking, touring, or any application where wheel reliability is critical.
What is the benefit of brass construction?
Brass offers a good balance of strength, durability, and resistance to corrosion, making it a preferred material for high-quality nipples.
How does the black electroplated finish improve performance?
The electroplating adds extra surface hardness to the nipple, increasing its resistance to wear and tear during tensioning and throughout the wheel's life.
Troubleshooting
Spoke feels difficult to thread into the nipple.
Ensure the spoke end is clean and free of burrs. Verify you are using the correct nipple type and that the rim threads are clean. The Loctite may offer initial resistance.
Nipple feels stuck and won't adjust tension.
The Loctite provides security; if significant force is required, ensure you are using the correct tool and applying steady pressure. If it remains stuck, it might indicate an issue with the spoke or rim threads. Extreme force could damage the nipple or spoke.
Wheel loses tension quickly after building.
While the Prolock feature minimizes this, ensure initial tension was set correctly and evenly across all spokes. Double-check spoke lengths and rim bed condition.
Pros and Cons
Pros
- Significantly reduces the risk of spokes loosening, increasing wheel durability.
- Precision manufacturing ensures accurate and reliable spoke tensioning.
- Brass construction offers excellent strength and long-term performance.
- The black finish adds surface hardness and a professional look.
- Longer length is beneficial for modern, thicker rim designs.
Cons
- The Loctite treatment means spoke tension cannot be adjusted as freely as with non-treated nipples.
- May require slightly more effort for initial tensioning or readjustment due to the threadlock.
- Primarily suited for specific spoke diameters (2mm) and rim thicknesses.
Setup, Compatibility & Care
These nipples are designed for use with standard 2mm diameter spokes. Their 14mm length makes them suitable for a wide range of modern rims, especially those with thicker profiles. When building a wheel, ensure your nipple key fits snugly into the flats for precise tensioning. The integrated Loctite threadlock will activate as the spoke is threaded in. While the threadlock is designed to allow for future tension adjustments, it is recommended to achieve your final desired tension during the initial build. Care involves keeping the nipples clean from dirt and grit to ensure smooth threading and tensioning. No special lubricants are needed due to the pre-applied threadlock.
Compatibility:
- Spoke Diameter: 2 mm
- Rim Depth: Suitable for thicker rims due to 14 mm length.
Care:
- Keep clean and free from debris.
- Avoid harsh solvents that could degrade the threadlock.
- Use a correctly sized nipple key for best results.
