I'm familiar with Italian, English, even Swiss... But what the heck is a Euro bottom bracket?
bmx slang for english bb
Yea BMX has a horrible habit of either creating standards or calling things by the wrong or a different name.
What about the spanish one?
But spanish BB isn't an off the shelf bearing. Specially made. Mid BB with a 19mm ID is off the shelf, Mid BB with a 22mm ID is a specially made one as well.
