Always had 6-bolt wheels and rotors and thinking about getting some Shimano factory wheels (MT66 29er) that have the centre-lock system; do the locking rings come with the wheels – or with the rotors that I’ll have to buy too..?

Thanks.

The lockrings come with the rotors: the hubs and wheels just have a plastic cap over the splines of the centerlok bit. The exceptions to this are the front 15 and 20mm hubs and wheels, which have a different lockring (with a bigger hole through the middle to accommodate the larger axle) that does up with a ht2 bottom bracket tool.

Many thanks, Julian.
