Before and after pictures, just for the record.
These Cyclos with their reversed internals are really amazing. Because of the way the pawls are held in place on the outer body and the depth of the ratchet teeth on the inner body, each pawl makes a "CLICK-click" at each tooth when freewheeling. The second "click" is subtle, but it is there.
