SRAM Centerlock External Spline Lockring
The SRAM Centerlock External Spline Lockring provides a simple and secure way to mount your brake rotors to any Centerlock-compatible hub. Designed for mountain bike applications, this lockring allows quick installation and ensures your rotors stay firmly in place during demanding rides.
Featuring a 44 mm / 16-notch external spline design, it threads onto the hub using a standard bottom bracket tool. Note that the external spline version may create clearance issues with some road forks, so it is recommended for MTB use only.
