Why? It isn't too far off from DIY hub bearing replacement. Yes, many times it is cheaper to just buy a new BB, but for the expensive stuff like Campy and Sugino I would go for DIY replacement if I can order the appropriate bearings. The guy in the video used a BB30 to BSA adapter to remove the fixed cup from the unit, so anybody can do the same with a BB shell hacked off a dumpster bike. It just takes a little ingenuity.
