I've searched and found some information on this, but thought I would drop it out there and see what someone that may have tried this found...
So I have a squeaky / creaky Hollowtech II BB. I was searching around for some new bearings for it. I'm not 100% sure they are needed yet, but... I've ran into the whole ABEC rating system. The difference between the 6805-RSs that fit it are pretty significant when it comes to cost. I know the difference in rating system is the tolerances held, I'm just curious if anyone tried both and seen any difference?
Best deal and can't beat the customer service! +1 for Enduro
ABEC 7 Rated 6805-RS Sealed Ceramic Si3N4: $48 each
ABEC 3 Rated 6805-RS Sealed Ceramic Si3N4: $24.95 each
A link to a site that thinks that the ABEC rating will have no effect on a low RPM less precision application, which is my first thought too.
