Unfortunately no (the answer becomes yes only for certain Fulcrum products). We released our N3W standard for free and the drawings are public. All the hub/wheel manufacturers can adhere and produce our standard upon a licence request form to fulfill. What we force with our drawing specification is just the freehub outer geometry to match with our cassettes. Every hub producer then has a different interface between the freehub and the hub axle and its own engaging mechanism. That's why our N3W freehubs are not compatible with third party wheels.
Please, check the list of N3W producers at the link above if you need a spare part for your third party wheel.
