mavic deemax bearings

[freeriding]

hallo!

i have a 2012 mavic deemax ultimate wheelset.

in the back wheel, you can adjust with a special wrench the bearing.

what is the function of this?

i notice that when i go full clockwise and I spin the rear wheel, it seems a bit draggy, and it stops relatively fast.

when i go full anticlockwise, it spins for a long time but there seems to be a bit of play laterally.

Preload adjuster.

You can just use a circlip tool, or 2 allen keys to adjust it. Mine always comes loose so just a heads up, check it after every run...

it is the QRM+ system by mavic:

- Quick adjustment according to performance goals: precision "free" adjustment for maximum fluidity, or perfect high precision setting for all-weather rides

the question is, if i let it be loose-so there will be some lateral play, can the bearing/hub be damaged?

Why would you want lateral play?

Just adjust it in the middle. Take the wheel out of the bike and feel the axle. Adjust it until you can't feel the axle shake around but before it gets too draggy. A slight amount of drag is usually okay, but just very slight.
