Ceramic Bearings II

I would like echo all that you have said and thank you for taking the time to write.  The ridiculous talk about Watt savings (from bearing choice) by the many can not be stressed enough.

Thank you Mr. Oz cycle for producing at great synopsis on bearings for cyclists.  It is a very big subject of course.  Let us hope the video will reach a very wide market.  I think you stressed the facts and downsides of ceramic and hybrid bearings.  Good job. More can be said of course: how bearing fit (too much compression from the bore) is so important - explaining the failures of Press-Fit BBs etc, and maybe talking about the old days when a bike would have numerous oil ports/grease ports (yes, there are some components flying the flag).  Then we have to praise Shimano and others for still producing great cup and cone bearing components but then 'sadly' throwing down the drain by forgetting to set the cones to the right tolerance in the factory.

There are far too many pseudo-engineers/designers in the bike industry who think their tertiary education means they are qualified.  Also they are probably having to compromise heavily and have to throw stuff out the door prematurely often - the disclaimers and lawyers will take care of you so you can sleep at night.

If you are young and want succeed in competitive cycling you better learn and practice to be the one of the best mechanics before you can afford to have one and pay for his or her life long experience.
