Of the standards we do have a large percent of them go ignored by companies unfortunately. In the end this mainly hurts the end user as we're the ones who get to try to figure out solutions or buy different parts in order to ride.

Unless its been changed, the bearing seat depth is called out at 10mm, if I remember correctly. So taking that into account, the spacer is the correct width. Are your bearings flush with the shell or are they sitting below the face by 1mm?
What did you use to install the bearings?

TOUCHE! exactly what i thought as well, i had the assumption that once i tighten the cranks down, the bearings would be pushed in to accomodate the 'extra' 1mm on each side but that's not the case thou.
I agree with the lack of standards in bmx, funny how when i got a new spanish bb set from a local company last night, the tube spacer is 50mm compared to eclat's 48mm....
I've ridden and work on bikes for ages now but encountering a problem with bb lengths and bearings are definately a first to me, thought i had all of these settled when the euro bb got phased out eventually but nooooo... hahahaha :confused:
