I think the quality of some of the bearings out in the market today is part of the problem. My next set of BB30 bearings, I am going to buy the best most expensive bearings I can find. I just wish Chris King or Phil Wood made BB30 bearings.
Agree...some poor BB30 bearings out there right out of the box. ABEC-1's are destined for a short, noisey life.
Biggest mistake out there isn't about pushing bearings in far enough or even using loctite...its not providing adequate crank preload. Same firestorm wages for Campy UT cranks with threaded BB's if insufficient preload...they can make noise. There is a gent on the web that sells shim kits because Campy doesn't supply them with their cranks like other crank mfr's do.
