Capo Exakt (1st style)

Capo Exakt (1st style) main image

The Capo Exakt was a well made copy of a 1950s Simplex Tour de France, sharing the Simplex's basic geometry and rather sub-optimal pulley cage arrangement. However, the detailed design of both pivots was considerably better than that used by Simplex and the mechanical finish and tolerances were impressive throughout.

I think that this is an early example, with a flat main plate, round pulley wheels, conspicuously perfunctory branding and some kind of non-chrome plating (Zinc? Nickel?). All this points to it dating from a period of post-Second World War austerity and materials shortages. The reversed slot in the gear hanger plate may indicate that this derailleur was designed to be used in combination with a hub gear.
