The thing to realize about the White VBC is they REALLY mean VBC. Every single inner ring that White makes has a different BCD. They supply these little rampy things that are held in place with the bolt assembly. So every inner ring is made such that the bolt is just inside the teeth of the inner ring, so the rampy things are always in the perfect place to lift the chain off the inner ring when you shift up to the outer. You should not think of the White as a crankset with a proprietary big ring and any inner ring. They are both proprietary rings, for better or for worse. That nuance didn't hit home for me until I had a long talk with them at their booth at NAHBS. Now I'm really eager to try a set, but I'll probably stock up on rings if I do.
