Edited: Corrected wrong bearing info..
Thanks blackpearl, I have been researching the hell outta these things today. I'm liking what I've been reading about Micro Blue and their coatings they add that "change the way lubricants work", keeping them contaminant free longer, reducing friction/heat even more, increasing longevity.
I read that the ceramic ball bearings are about 3x stronger & 60% lighter than their SS counterpart (a general consensus), though elsewhere, I read that if they're taken past their point of fatigue then they can all just shatter instead of one or two slowly grinding down as with the steel ones. Though that seems like disinformation to me, since ceramic bearings are just SS balls inside a ceramic coating. Maybe they're speaking of the actual coating breaking down? Just speculating some..
There was more info about "full ceramic" bearings (ceramic races & bearings) in other articles/forums, though it appears that they are not recommended at all for the demands of wheels, because they don't have the strength required.
Really, there are articles and opinions all over the place with this stuff. It's hard to determine what is honestly the best choice. I know either full ceramics Or hybrids are much lighter than the traditional steel bearings, taking less force to turn, thereby improving performance and decreasing friction/heat, either way you go. One guy that tested this stuff said he was seeing gains of about 3-4 HP, but about 5 lbs in torque with a 1000cc bike (GSXR I believe), when swapping the same wheel for hybrid ceramic bearings. Though the felt effects of acceleration, braking and flicking the bike into turns is supposedly quite noticeable.
So, anyone that really knows about this stuff, feel free to chime in. Gotta get the ball rolling, so to speak, asap. I want to make a purchase tomorrow if I can get the info I need to make an informed purchase. Gonna keep diggin away for now.........
