Capo Exakt (2nd style)

Capo Exakt (2nd 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, partially complete, example is from middle of the period of production, with a flat main plate, but with toothed pulley wheels, a fancier logo and lush chrome. In my first example the head of the tension pulley bolt is on the outside with the nut on the inside. On this example the bolt head is on the inside and the nut is on the outside. I do not know which is correct.
