Hey guys...just got a set of the new V2 rear hubs...can you please confirm tight fitment (I used some sandpaper in the inside of the arms for free movement) and that the brass crash tube is no longer used between the bearings?

Mine was tight as well, besides sanding the arms I sanded one of the 1mm hub shim's down to .80mm

I used the crush tube.
