The conical hub was Triumph's rear hub design used before the disc-brake hubs came along, and this sprocket is specific to that hub pattern. If you're rebuilding a rear wheel or just replacing a worn sprocket, this is the part number to work from.
We don't have much more detail on file for this one beyond the tooth count and hub type, so if you've got questions on exact fitment for your bike, give the shop a call before you order.
