For months now I have maintained there is a big difference in the quality of the new rear bearings verses the original ones. Today I had time to compare an original FAG (Germany)and a new SKF (Italy) bearing shells. MY conclusion is what I suspected, the new ones are NOT the same. I took pictures and measurements to document what I saw. I hope the pictures let you see the difference. Guess which one is the original German one!

Bearings have a shelf life due to the grease aging out. That's an easy fix. Replace the grease. You have to grease the front wheel bearings anyway and the boxter spec racers are replacing the grease on the rear bearings with new and more before installation. There's a video or two on how to repack a rear hub bearing.
