Cassette/rotor lockring tool question

[hypnos]

I haven’t needed any new bike tools in a very long time. My new White Industries hubs are a completely new thing for me. I am able to install the Ultegra cassette and front rotor lockrings with my Park FR-5 lockring tool; however, the hole in this tool is not large enough to clear the axle and engage the rear rotor lockring. Do I need the Park FR-5.2 lockring tool? Is the hole large enough to clear the rear axle? If not, what do I need?

I went through this same problem with my first disc bike.

Two possibilities:

1. Pull the endcap and use your existing internally-splined lockring and install with a cassette tool. But I'm not sure if White Industry hubs have endcaps that are easy to remove.

or

2. Switch to externally-splined lockrings and install with a new tool like Park's BBT-9.

Try looking at the Park Tool 5.2h. This is what I use to install my Shimano cassettes and rotors on my White Industries hubs.

I was looking at that model. There would be no way to use my torque wrench but that would not be okay, I assume.

You got a double negative so I'm not clear exactly what you mean. For me it would not be OK to not use the torque wrench I think.

I've got enough history with cassettes coming loose or creaking when not torqued properly I wouldn't trust many people to get it right without a torque wrench at 45Nm with a wrench that size. (though I can't really tell how long it is from the picture)

I had totally not thought about this but will have to deal with it at some point soon. My MTB has a 12mm thru axle on the back and whatever version of the park lockring tool I have I bet it doesn't fit on the thru axle. (I have the one with the guide pin)

My cassette and front rotor lockrings have been torqued to specification. The rear rotor lockring will be the problem.
