that's great fouled but im having trouble figuring out how. if you put one set of bearings in then the hub will touch the carrier before it touches the bearing, in my case anyways. I would like to see if I can get someone to measure there brake or sprocket hub to see how far it reaches inside the carrier or if someone would measure their 40mm carrier to see how deep the bearings sit. here is what im working with
13.2mm
13.53mm
