Product Information
Full details
The Hope Centre Lock Disc Lockring is an essential component for cyclists running centre lock rotor systems who prioritize precision engineering and lightweight performance. Designed for durability, this CNC-machined lockring ensures your rotors are securely fastened to your hubs, making it an ideal choice for both maintenance and custom bike builds. A key caveat to note is that this specific model uses an external spline interface, which requires a compatible bottom bracket tool rather than a standard cassette lockring tool for installation.

Troubleshooting
Tool slipping during installation
Ensure you are using an external bottom bracket tool and that the splines are fully engaged before applying force.
Rotor feels loose after tightening
Verify that the rotor is fully seated on the hub splines before tightening the lockring; if it persists, check that the hub splines are not worn.

Setup, Compatibility & Care
Installation of the Hope Centre Lock Disc Lockring requires a standard external bottom bracket tool (such as those used for Shimano Hollowtech II). Begin by ensuring your centre lock rotor is correctly seated on the hub splines. Thread the lockring on by hand to ensure it is not cross-threaded before applying the final torque. Always refer to your hub manufacturer's torque specifications, typically around 40Nm, to ensure the rotor remains secure. Periodically check the tightness of your lockrings as part of your pre-ride safety inspection, especially after aggressive riding or bike transportation. Keep the threads clean and lightly greased to prevent seizing over time.
