One of the old bikes I fixed up recently had a disturbingly small number of headset and bottom bracket bearings, something like 14 in each headset retainer and 8 drive side/7 off side in the bb. I am accustomed to seeing many more, maybe 20 each headset and 11/10 bb. Headset and bb use the normal 5/32" and 1/4" bearings. Retainers are available for up to 22 5/32" in headset and 11 1/4" in bb. ASSUMING the retainers are the right size (they seem to be more or less universal), is there any downside to replacing the current retainers with some that accept more bearings.

BTW, I choose to use retainers.

Thanks,
Raymond
