Hi all, Im buying ACL Race Series bearings for the mains and big end. . The bloke on the phone asked if they were standard sizes, I assumed yes as they are going into a standard RB30. . ? Do I have to check clearances or something or do I just order the standard sized ones? Thanks, Josh

dude if ur just doing a frshen up then u need to take the old ones out and check if there standard. its stamped on them, if the crank has been machined then they will be over size which will also be stamped on the old berrings. dont guess dude as if its wrong it wont even last 1 minute when first started
