Dacon hub-derailleur converter
Author Bill IvesThe Dacon converter is a driver which replaces the
Sturmey Archer driver and dust cover. It takes Suntour New Winner
sprockets so there is a good range of potential sizes. It will take
three sprockets with a standard axle and four sprockets with a long
axle. There is a piece about the Dacon in Tony Hadland's Sturmey book
in which he implies it was in production in 1985.
