Fitting Campag AFS rotors to CK R45 CL disc hubs

[Eleven21]

The campagnolo afs rotors don’t come with centre lock rings but I think I’m safe in saying a Shimano lock ring will suffice.

Will the internally splined Shimano lock ring work? Or will i need lock rings with external splines?

Thanks

The Chris King website says to use the externally splined HB20 lockring and visually I would concur with that. Both ends of the axle seem to have collars or collets on them even though the axle does taper a little bit. I can't imagine the cassette lockring tool would fit over the collar.

I had this very problem with White Industries CLDs. I needed to get special axles made with the radius at the ends reduced so I could use the internally splined lockrings with the hubs. The HB20 lockring would scrape my Emonda SLR's fork leg, and I had to temporarily use one with the edges ground away.

I did check the Chris King website. The only mention of a rotor lock ring I could find was this

That’s great thanks

If the HB20 lockring is too big (ie, it contacts your fork), you can take the lockring from Shimano’s 6-bolt to centerlock adapter kit (SM-RTAD05). The lockring in that kit is also externally splined, but is thinner than the HB20. That’s what I had to do for my TCR combined with a DT-Swiss 240s front hub.

Thanks for tip.

It is the external lockring. The hb20 is the thickest one. This is the thinnest Y24698030

For general information, Campagnolo now sell the AFS lockring as a loose spare, Campagnolo part number M1-101
Shipping to SCs and distributors early 2020

Note the AFS lockring would work with Campy/Fulcrum AFS hubs only, not the center lock hub of Chris King (or any other brand).
