Shimano's Centerlock to 6-Bolt Disc Rotor Adapter is a pretty straightforward article. It slides onto the centerlock mount on your hubs, leaving an interface to mount a six-bolt rotor.
It includes a six-bolt washer, a lockring, and a circle clip to secure the conversion, and a standard Shimano lockring tool is all you need to install it.
It's a home mechanic's job, but note that each kit only adapts one centerlock hub, so you'll need two for an entire bike. Please note that this kit is not compatible with most 2-piece rotor designs.
