Ceramic bearings are just like any other bearing in that they vary in quality. U get good ones and bad ones. As a rule the more u pay the better the quality

I cannot recommend the high end boca kits enough.
Yes very expensive. But they really last. (five yrs and still like new)
They require zero maintanance, just wipe any debris off the outside. That's it

Boca state not to flush them and not to oil them as the seals are self lubing
They are so much smoother than anything else I've tried and have zero play in them.
What's £120 if they can last so many seasons and give u a performance boost,
Or at least stop any dnfs from bearing failure.
Hell we tend to pay more than that for a speedo and five yrs is a very good innings for one of those!!
