Just saw the article on headset bearings, as a guide, how often should these be greased up? Are they something that will generally take a long time to wear out? Obviously neglect and water entering the bearing would severely limit their life, but are they generally something that last a long time?

    I have an MTB which is now 11 years old and the headset still spins perfectly despite never having been dismantled. More surprising still is that it still has the original bottom bracket.

    The kid's cheaper bikes are always needing these things servicing / replacing.

    I think it depends much more on the quality of the seals than on the bearings themselves.

    It does depend on the quality of the seals. Chris King you just fit and forget, cheap ones you will be cleaning the lower bearing very frequently, especialy if you ride without mudguards.

    Unless you ride a lot in the rain, once a year might be a good idea - if it is still ok after a year you should be ok to leave it alone.

    If riding without mudguards in winter, you'll be lucky if they last a year, never mind servicing them. Check them at least monthly - loosen the stem and drop the fork to check condition - regrease and refit only takes a few minutes. You can pop the seal and repack, but very hard to restore a bearing if it's rough - swap the top and bottom bearings if you can extends the life

    If your headset has ball bearings in a cage, take the cage out. This helps stop indentations/pitting forming on the bearing races.
