The ICS shaft assembly is all sealed bearings. There is a simple tool which assists in un-threading the double freewheel from the shaft, let's say for cleaning purposes. Everything else on the daVinci is just normal stuff with one small exception: The chainring stack is held together by a custom, steel 12t chainring which threads on. Frankly, I'm not aware of tooling that supports taking this assembly apart. Put a lot of torque on that small chainring it's on very, very tight. I believe daVinci is working on an alternate assembly technique similar to the stack on a cassette. If you're interested you might check with Todd at daVinci.
