Centerlock rotor installation tips please

[NHAero]

About to install Shimano XT centerlock rotors onto DT Swiss 240EXP hubs.

Splines - grease or antiseize?
Lockring threads - grease or antiseize?

Other tips?

Thanks

I've found regular grease is fine. Don't go overboard with it though. I use park tools generic grease. I'm sure anything is good.

You might know this, but I didn't. Don't try to use a bb socket, for some reason they designed the centerlock rotor rings to not work with them even though they have the same form factor.

Get a bb wrench that's open http://www.birzman.com/products_2.ph...cID=28&Key=129

Grease things that move
Anti Seize things that don't move (but don't require locktite).

People grease rotor/hub interfaces? I never bother.

That would be a better rule if anti-seize wasn't mostly grease.

Both Shimano and ParkTool say not to grease centerlock rotors.

I assume advice not to grease centerlock lockring threads is out of concern for grease liquidating as braking heats it up. I generally film the threads with marine grease but use it very sparingly. So far no issues.

Does this only apply to Shimano? I’ve used a bb socket with both SRAM and SwissStop center-lock rotors without any issues at all.

Yea. I read that after my initial installation. However. I've never had issues. But again. I put very little. I'm assuming they don't want people to slap on a wack load of it. It flings into the rotor and pads.

Thank you. I had a Wheels Mfg wrench that fit nice and snug.

Some bb sockets might not have as much chamfer as others. And also, the lock rings are not all the same. But I think if you mention this to a bike mechanic they will nod knowingly. I had problems with my DT Swiss lock rings coming loose before I switched wrenches.

Don't get grease on the rotor.

Pro tip.

No grease on the splines. Very light grease on the threads.

Depends on the lockring. There are both internal (cassette locking) and external (bb) style although the former may have gone away with Q/R axles. I have an open ended old shimano spec bb tool that works great for the latter.
