Good luck finding a Cyclo-Benelux triple cog for a Sturmey hub, they are very rare these days... it took me 26 years to find this part, after the bike I built around this drive train was stolen. Thank you, jonwvara ! I have a choice now of a Sturmey Archer FW four speed or a Sturmey Archer Sprinter Elite five speed to use with this cog set. Decisions, decisions, decisions........
