Problem Solvers Centrlock Adapter
These adapters allow the use of 6-bolt rotors on Shimano's Center Lock hubs. We've got two versions: one for use with a standard Center Lock lockring (BR0381), and the other with a pinch-bolt for hubs that have buggered threads (BR0380).
Our standard Center Lock adaptor sandwiches the rotor between the adaptor and the lockring - this works great for non-damaged hubs. If you have messed up threads, our pinchbolt version is the way to go! For easy installation of our pinch bolt adaptor (BR0380) use a cassette lockring installed over the adaptor to push it all the way onto the hub, then tighten the pinch bolt to proper torque. Next, remove lockring and install your rotor. This method helps ensure proper adaptor and rotor alignment.
