is this the wrong lockring to use with an r45d hub?

[bitt3n]

This video shows a Chris King R45D rear hub with lockring installed. You can see how the adjustment cap (that bulbous silver part) sits flush with the lockring:



On my hub, it does not sit flush with the lockring. There is about 2mm of a cylindrical part of the adjustment cap that doesn't slide beneath the lockring:



This causes the rotor to hit the caliper (even without the pads installed and the mounting bracket pushed all the way out):



I notice the guy in the video is using a different, thru-axle only lockring. I'm using a QR hub and the internal diameter of my lockring is insufficient to accept the cylindrical portion of the adjustment cap.

Can someone help me figure out whether I am correct in my assumption that I have the wrong lockring, and if so, which lockring I need to get the cap to fit, given I can't use the thru-axle model in the video?

Why can't you?

My understanding was that I wouldn't want to use a thru-axle lockring on a quick release hub, but I just called Chris King and that's what they say to do, so the answer to the question is to use part SM-HB20 despite the fact that it says it's incompatible.

I think what you're reading is that only that lockring is compatible with 15mm and 20mm thru axle hubs not that the lockring is incompatible with QR hubs. Regardless, it is compatible. DT Swiss has a nice centerlock to 6-bolt adapter (nice to have around) that uses the same lockring. If you buy that it's like getting the adapter for free.

The one in the picture/video is different than the one you posted.

The one in the video is for a thru axle. Says so on the lockring.
the one you posted a picture of is a standard version for Shimano hubs. They don't fit everyones. Especially if it has a large or oversized axle like the CK hub does.

You need this one.

Ah yes that seems to be the source of my confusion. It's only compatible with certain thru axles, rather than compatible only with thru axles.
