Hello.

Time to change the bearings in hub and wheels but I can't find the same brand with the same measures (6902, 6903). In order to replace the bearings, is it just enough to choose the right measures without any further considerations?

The bearing to replace are LBLU type, I don't know exactly what it means, I guess it regards the type of seal, while usual is 2RS. I know there are some other characteristics to bear in mind, like tolerance and ABEC scale, which seems to be 3 for bicycles.

My fear is that the bearings I purchase, although the same measures, will not perform good enough as current ones, not because of quality difference but because some other reason.

I'm attaching a picture of one of the bearings, disassembled.

Thanks.
