Chain-pull type, resisted by a coiled leaf spring. Range was for 3 or 4 cogs. This 1952 Benelux had a shortened and cranked arm compared to the 1950 Benelux, designed to provide closer contact between freewheel cog and jockey pully for better shifting. This 1952 Benelux with an alloy arm, was followed by a 1953 Benelux with a steel arm instead of alloy. These derailleurs were similar to a 'Sport' model, which had a super-finish arm with an enameled upper pivot bolt head.
