The stock BB that comes with Omniums are a crap shoot - some of them seem fine and others total junk.
There really isn't any trick to installing them, you just tighten the bolt and go. If the frame has a BB shell that's a true 68mm, the crank arm will bottom out on the spindle before the bolt becomes overtightened.
