history - Why are bearing ball sizes measured in imperial units? - …
@Criggie Finding metric ball bearings isn''t hard at all - it''s just hard in a bike shop. I''m asking why bikes are designed with imperial ball bearings when they are otherwise metric. France''s attempt to make everything a metric standard in the 70''s was a flop too, but they never tried to make metric ball bearings.
