I think that this is another Brazilian derailleur dating from the late 1970s, when the state of the Brazilian economy made it impossible to import Japanese product. What exactly the word ‘Cristim’ is, I am not sure (Brand? Model?). I have been unable to detect any references to Cristim anywhere.

Even though this is only part of a derailleur, there is a whole lot going on. The basic design apes the SunTour Honor, complete with Quick Cage. The positioning of the cable outer stop, cable clamp and adjustment screws are pure Shimano. The man-size, slotted heads on the adjustment screws have a whiff of Dimosil about them. The distinctive curved shape of the cut-out at the tension pulley end of the pulley cage recalls my other Unknown Brazilian models.

And then of course there is the Arabesque patterning - a fulsome homage to the unforgettable Shimano 600 EX Arabesque.

Like one of Tarantino’s less interesting movies, this derailleur contains so many allusions to famous classics that it almost forgets to have any plot of its own.
