Hi All,
I have been in contact with Richard about these and thought I should post for all.
Both of these BB's use the same cartridge style bearings. It is an easily found cartridge #6903. I prefer the Enduro type that I get from QBP, They sell for about $10 each. I have used them in both BB's without problems. That being said, I would send in a Phill BB for them to press in new bearings in the future. They charge $35 to do this. I am not convinced that my bench vice presses the bearings as straight...
The OMAS ones are not pressed on the spindle, so no vice is needed.So, If you need OMAS bearings, head down to your LBS and have them add it to thier next QBP order.
Speaking only from personal experience,
