Best forget about these hybrid bearings for a while.

The biggest problem is drag from the seals.

A ceramic bearing in itself does very, very little in creating a less drag as it's only the material of the balls that is being changed.
Further is that on some hybrid bearings the balls itself are rounder and that is more a performance gain than the ceramic itself allthough the gain is in perspective and should be taken very seriously unless you are the female version of michael rasmussen ....

The real gain comes when these bearings become full ceramic than there is no need for any lube to use and no use for dustshields.

Either save you money or spend it on PW bearings they have a reputation or remove one of the seals in the back of the bearing cup that will do a lot more for a lot less money.
