    hallo. i have 2012 deemax ultimate wheelset.

    I notice when I spin the rear wheel, it seems a bit draggy and it stops relatively fast (compared to another bike with a hope rear hub). (it is not the disc rotors cause i have them detached)

    (if i remove the wheel, and spin in it in the opposite direction, then there is no drag, almost no friction, so i guess it has no bearing issue- furthermore the wheels are almost new)

    (so with all the facts above, i guess it has to do with the freewheel when it is engaging)

    is this just the way Deemax rear hubs run or should i do something, like putting some mineral oil in the freewheel?

    i had a set of dee trak wheels years ago, similar issue. freehub drag. i could never get it properly adjusted, and broke a few deraillers in the process. eventually i just cut the sh*tty mavic hubs out and laced the rims to hadleys.

    A 2012 Deemax should have Mavic's ITS-4 freehub which is light years better than their older/cheaper hubs. Sounds like an adjustment issue to me.

    Pull off the freehub body, clean it out, and re-lube it with mineral oil.... Make sure to get some on the main seal too, that should help a lot. Mavic freehub bodies require a lot of attention.

    Also, take a look at this video to see how the hub works -
    If I had to guess what was going on I'd say it has to do with bearing preload. I would back off the bearing preload ring on the non-drive side and make sure the axle is locked together properly (cone wrench on either end of the axle) and then re-adjust the bearing preload as per the video.

    In 2006 sure. Their design now is pretty much just like about 100 other hubs.

    Dogboy's on the right track.

    so you guess the preload is too much? it may be :)

    1. when adjusting the preload, the video indicates to stop when contact happens. what does this mean?

    2. if i put very little preload, then it will spin almost friction free? is there any danger in little preload?
