OK, i need an issue cleared up, with standards to bicycles threads (for bottom brackets). I have checked "sheldon Brown" but i really did not get my answer..
Correct me if i'm wrong:
English/British/Euro: The standard MTB and road.And some BMX
Ashtabula/American: old school BMX
Mid: standard BMX
So my question is wtf is this "spanish" style bottom bracket?
Secondly, by my this logic will a Euro BMX bottom bracket thread into a MTB bottom bracket shell?
