French Patent # 792,365

French Patent 792,365 - Cyclo main image

This is a patent for a bizarre design that looks like Cyclo’s take on a simple, possibly cheap, racing derailleur. A kind of ‘suicide’ rear mech.

The long arm is moved across a gate with three different slots - see figure 6.

I don’t think this mechanical marvel ever made it into production, perhaps we should be grateful.
