steve:
ok, so i am not rambling on now, nut

TAKE NOTE - BEWARE!!!!!

if you take a tube spacer that came a euro bb and try fitting it into a usa bb
-they are different

also the other way around too

-one is too big one too small

-this is probablyy the reason why they get fackered up, as on the one hand the spacer is too long and the cups wont go in
-on the other the euro is too short and they pull the bearing races over as you tighten the arms
 :LolLolLolLol:

again you can pipe slice 2mm off one to fit - be careful though

lodge:
I have priced profile bearings at bearing factors they range from 8 to 25 notes each depending on quality which is annoying because a similar size metric bearing is about 90p. You can buy six R12 2RS bearings off the bay from the states for 11 quid posted.
