You just have to love this Luna Ciclles derailleur. It is an unabashed copy of the ubiquitous Huret Eco, one of the dominant inexpensive derailleurs of the late 1970s and early 1980s. But the Luna Ciclles has its own charms; a ridiculous name, extravagant 'Drillium' pulley cage plates and adjustment screws that are perfectly sized for The Incredible Hulk. Despite all those holes in the pulley cage plates, it cunningly manages to weigh 3g more than the undrilled Eco - that's sheer panache.

When I first saw it, I thought that the 'crescent moon and star' form of the 'U' in the word 'Luna' might indicate that it originated from somewhere in North Africa. I was hoping it might be the first African derailleur in this collection. But it seems that it was not to be - I have been assured that Luna Ciclles were manufactured in Portugal.

In the main photo, I have released the pulley cage spring so that the derailleur could take up a more normal configuration.
