Sturmey-Archer SW Drei-Gang-Naben: Unterschied zwischen den Versionen

gear rings At least three planet-cage designs were fielded over the years, with the original design having a smooth outside diameter adjacent to the low-gear pawl sockets. (This configuration appears in the illustrations of the 1956 master catalogue.) Later, a thin ridge was added next to the pawl sockets, presumably to aid in the centering of the planet cage relative to the ratchets, but possibly also to improve the gear alignment. The last change was apparently to increase the width of this ridge to reduce the attendant wear. This feature may be the big reason these hubs were not known to give too many "skipping" problems in low gear.
