Best to unscrew it and check the condition of the threads.
Most cassette lock rings go to 40nm, which is not particularly high effort with an automotive torque wrench.

I try not to undo it unneccessarily if I can, just because that thin "foily" washer on the lockring tends to get damaged a lot. Thus I wanted to just leave it for now until my proper 2-60 Nm digital torque wrench arrives.
I do not trust that automative torque wrench that I borrow I think it is very approximate.

Washer can be replaced to washer from spare cassette lockring,
and it can be ordered online as separate part Y10Z04000:

I guess, to simplify:
If I torque that lockring to a crazy torque, what will give up first? Lockring or freehub body threads?
Can it do any other potential damage?

I bought a second hand cassette where the lockring was tightened by a gorilla. The lockring got flattened. Il see if I can find it.musiclover wrote: ↑Sat Oct 02, 2021 1:53 pmI guess, to simplify:

on an aluminium DTSwoss freehub body, the freehub threads will fail first iv you're using a Shimano steel lock ring.musiclover wrote: ↑Sat Oct 02, 2021 1:53 pmI guess, to simplify:

I've also seen longitudinal splits from over tightening (novatech iirc) and the end 5mm of the freehub shear off (hope).
I think you've missed my point.musiclover wrote: ↑Sat Oct 02, 2021 1:17 pmI try not to undo it unneccessarily if I can, just because that thin "foily" washer on the lockring tends to get damaged a lot. Thus I wanted to just leave it for now until my proper 2-60 Nm digital torque wrench arrives.

If there is an issue with how your cassette has been fitted to your hub and you do not find out for a while, then you may be paying out for a lot more than a thin "foily" washer. Think new hub....

That just happens because it happens. The design of Shimano HG cassettes on an aluminium freehub inevitably leds to the cogs digging in to the splines and cranking down on the lockring will not prevent it.musiclover wrote: ↑Sat Oct 02, 2021 12:40 pmI have a Shimano Ultegra cassette on a DT Swiss 350 hub, the freehub body starts to show damage from the upper cogs of the cassette. I have been told that this happens due to the lockring not being tight enough.
I just noticed an issue with a 350 hub on a set of DT Swiss wheels aquired last year, and found this thread via searching.
The SMALL tooth gears of an Ultegra cassette were "stuck" on the 350 hub. [I originally typed "large tooth gears"] Once I was finally able to remove them, I noticed that the hub was damaged where the cassette was deforming the hub splines, so I had to file down the areas that were damaged. This is my first set of DT Swiss wheels, and I have never had this happen before with other wheels that also use aluminum hubs.

It makes sence though that a tighter fit of a lockring should limit the cassette movement. Have you been adhering to the torque recommendation and still had the same problem? What is the information that a lose cassette will do the same damage as a properly torqued one based on?
Large cogs are on aluminium "spider" and thus the freewheel body is not normally damaged there. That's odd.CAAD997 wrote: ↑Wed Oct 13, 2021 9:02 pmI just noticed an issue with a 350 hub on a set of DT Swiss wheels aquired last year, and found this thread via searching.

musiclover ........ I have corrected my comment as it was the smaller toothed sprockets that caused the issue.

The smaller sprockets are steel, and the steel sprocket splines created some deformation on the aluminum hub splines.
Since this has not happened with my previous wheels [multiple sets from a different manufacture], I was searching here just to see if I could find information about this being a specific DT Swiss hub issue, or maybe it was just a one-off issue. Worst case for me is that I just need to replace the hub.
The cassette was an Ultegra CS-6700 10-spd (with the appropriate spacer) - just switched the cassette to an 11-speed and plan to look at it in a week or two to see if the 11-speed cassette has created damage.
