The most important thing after the threading, as someone pointed out, is making sure you get the correct BB for the crankset yu intend to use. If your going to use a Super or Nuovo Record crank then you need a Super or Nuovo Record BB. If you using something newer like a Mirage or a 105 then you need a Mirage or 105 BB to match that crank.
