Hubs and sand/grit

Hello I have a Haro XC hardtail with the stock disc hub wheels. They are branded Pivit but I assume are the same as these

Where I live is very sandy/gritty as they quarry it nearby. It is obviously mixed into the mud when I ride. Is there a problem anyone else has found and can it damage the hubs? Also is there anything I can do to stop any damage? I understand that these hubs or Shimano M475 are the most common disc hubs as they appear up to about the £800-900 mark. Thanks

    Those hubs are not the best, the 475 is a bit pants too.

    Grit and sand can ruin stuff a lot quicker. The only way around is to service them regularly and not wash any grit back in. The better (more expensive) a hub generally the better sealed it is - but nothing will keep out the really fine stuff.

    Those seal fine. Just clean or hose any grit off after riding. I also make sure my hubs have plenty of grease, as it seems to stop muddy water getting inside.

  • Hi thanks for the quick reply. I mainly ride on the road in the winter but will add some more grease and wipe them down regularly. Thansk

    yup as said above, just clean and service regularly.

    Just make sure when you're cleaning the bike don't use a high pressure jet pointed straight at the bearings. This will wash out the grease already in there.

    What jairaj said. And if you take the seals off to lube, make sure you fit them back on properly.
