How does your hub put the DS hub bearing where the arrow is at the end of the axle? That's pretty cool. Does it use a bushing under the freehub? Most hubs have two hub bearings and then two freewheel bearings all on the same axle (viewed left to right). All stiffness comes from the axle. The only ones I know that have the hub bearing on the outside are DA hubs (and I'm not sure the newer ones do that). There's a new Alchemy hub that has the DS hub bearing in about the middle of the freehub. Because the hub body takes up room under the freehub, one of the freehub bearings is a bushing.
