True, the level system is proprietary with their hubs and cog.
If he's going to keep the stock redline wheel / hub then just getting a tomicog should do the trick. I was posting more for if he was thinking about rebuilding the wheel, or for people reading about tomicog and thinking of building a wheelset from scratch with a mb disc hub.
