I wore out loads of Rotor bearings (and posh aftermarket bearings) and now use: https://www.sigmasports.com/item/Wheels-Manufacturing/BSA-30-Bottom-Bracket-Steel-Bearings/EQ65
Is this basically a better version of the Rotor BB that does the same thing?
I don't know if it's better but I seemed to kill bearings fast in my Rotor BB cups. I was riding across 2 continents a year at the time though...
