In the 1970s Huret produced quirky derailleurs mixing folded sheet metal with exotic materials and a certain, crazy, French, creativity. By the 1990s Sachs was producing solidly engineered derailleurs manufactured using quality materials. But, in between, there were the 1980s - and the, slightly confused, in-between, brand called Sachs-Huret. And it produced some, slightly confused, in-between derailleurs - like this Sachs-Huret Rival.

It's dull not quirky - a relatively poor imitation of a, decade out-of-date, mid-1970s Shimano. It uses more aluminium parts than your average Huret, but more folded sheet steel than a mid-range Shimano. And it weighs a stonking 259g at a time when a mid 1980s Shimano 600 came in around 200g. And, and, and, it's almost deliberately ugly.

Even the logos are slightly confused. The 'Sachs-Huret' bit is cold, clean, modern and angular. The 'Rival' bit is florid, traditional and extravagant.

• It has a short, 50mm, pulley cage.
