Any old front wheel 'brake drum' has these hubs 'incorporated' and would be easy to seperate and source to come by. Drumbrake-hubs might even have a better (narrower) track width too.
That would be the smaller bearing set-up, correct? Same option is not available in the big bearing?
Reality check, that half the population is smarter then 50% of the people and it's a constantly contested fact.
