SRAM Centerlock Disc Brake Lockring – Spline – Black
This SRAM Centerlock lockring is used to secure a Centerlock disc rotor to hubs that require an internally threaded lockring. It threads into the hub body from the inside and clamps the rotor firmly in place.
It’s the correct choice when servicing or installing SRAM Centerlock rotors on hubs designed for internal-thread lockrings, commonly used where axle or hub design limits external lockring clearance.
Key Features
• Designed for SRAM Centerlock disc rotors
