Spanish Patent # 184,448 - Zeus

Spanish Patent 184,448 - Zeus main image

This is the fourth in a series of Zeus patents for pull-chain derailleurs that feature basically the same hanger plate, cable routing and derailleur body. For this final version of the design, Nicholás Arregui Gallastegui faithfully copies the slightly curved body and sprung double pulley cage of the 1946 Simplex Champion du Monde 46.
