UT cranks don't really have a BB, they have empty bearing cups. The bearings are press fit on the spindles and merely slide into the cups. All UT cups have the same dimensions, so they are interchangeable. The SR level cups have no internal seals, so shouldn't be used with lower level bearings. Only the CULT bearings should be run without internal seals.
