friction slows anything down period! it aint rocket science.... less friction means less hp to move it. may be small and not worth it to YOU but once one has done everything else to their bike u look for small things to make the bike faster like less friction and less weight thru out the bike.....I have seen far to many aftermarket parts that are sold simply on the basis that they are better because... Ceramic bearings are in this group for me.
I'm glad that there are people that have plenty of money to spend, it helps keep the economy rolling along.
so because its a small improvement that you can't afford or don't want to afford that means no one else shud take the advantage of it? hey if ur too cheap or too poor to afford them then so be it but to state it has no performance advantage is just ignorant!
