A Centerlock system is a type of disc brake hub mounting standard where the rotor attaches to the hub via a splined interface, secured by a lockring. It is distinct from the 6-bolt system.
No, this lockring is specifically designed for hubs that use the Centerlock mounting standard. It will not fit hubs with a 6-bolt rotor mount.
The steel washer is included to provide a larger contact surface and ensure more even pressure distribution when the lockring is tightened, enhancing security and preventing damage to the hub or rotor.
You can use this lockring with any rotor designed for the Centerlock mounting system. Ensure the rotor's interface matches the hub's Centerlock standard.
You will need a specific Centerlock lockring tool, which is similar to a cassette lockring tool, and a torque wrench to ensure proper tightening.
Axle size typically refers to the diameter of the through-axle or quick-release skewer. You can usually find this information in your bike's specifications or by measuring your existing axle.
This lockring supports up to a 20mm axle, which is common on many performance-oriented bikes, including some e-bikes. Always confirm compatibility with your specific e-bike's hub and braking system.
Ensure the hub splines and lockring are clean and free from dirt or debris. Verify that you are using the correct lockring for a Centerlock system and that it is aligned properly with the hub splines.
Check that the lockring has been tightened to the manufacturer's specified torque using a torque wrench. Ensure the steel washer is correctly positioned. Re-tighten if necessary, adhering to torque specifications.
Ensure you are using the correct Centerlock lockring tool. If it's seized, apply a penetrating lubricant and allow it to sit for a while before attempting removal again. Be cautious not to damage the tool or the lockring.
Replace the lockring immediately. Continued use of a damaged lockring can compromise brake performance and safety.
Compatibility: This lockring is exclusively designed for bicycle hubs utilizing the Centerlock mounting standard. Ensure your wheel hub and brake rotor are both Centerlock compatible. It supports axle sizes ranging from 9mm, 10mm, 12mm, 15mm, up to 20mm. Always verify your specific hub and axle dimensions before installation.
