Rebuilding: Should I replace these bearings or leave them? (pics)
Hey everyone, hoping to get some advice here. I was all set to replace the rotor and fixed gear bearings, but I found a bunch of people suggesting it's better to leave the stock bearings, including this racing beat article that says:
Why is this? What is not safe about a new bearing? Not sure if this includes the fixed gear bearings?
Here are what mine look like.. What are your thoughts? I think both fixed gear bearings look toast, not sure about the rotor bearings... Any advice would be appreciated.

(I know this is where the join is in the bearing, but it was as good a spot as any to photograph)
In general, do not replace rotor bearings when you are re-using rotors unless they are over the recommended clearance or show some damage from dirt, heat, or lack of oil. Our experience has shown that used bearings in good condition are safer than new, untried bearings.

Well, I have a nice set of Mitutoyo verniers but they don't seem to go deep enough into the rotors LOL. I didn't know there were different bearing sizes when I ordered my rebuild kit from Atkins, as I recall there was only one option. I just checked the new, loose bearing against the e-shaft and as long as it doesn't shrink a bunch once pressed in, the clearance is right in spec. Guess I'll go for it!
