Which was my point. These have fewer bearings than the norm. The question is now moot. I have ordered retainers for 11 bearings each side bb and 22 headset. If I am wrong I will let everyone know. FWIW my favorite wrench said the more bearings the better (which is what I was thinking) as long as they are the same size and the retainers are compatible as to diameter, etc. I already have bags of new Grade 25 so the only risk is the cost of the higher-capacity retainers.
