General Information
The Hurét "DuoPar" touring derailer had two parallelograms (hence the name.) The extra parallelogram was used to move the jockey pulley up and down, permitting the DuoPar to handle a wider gear range than any other rear derailer before or since.  The original version was quite expensive and utilized a lot of Titanium.  As a result it did not sell very well.  The DuoPar Eco was then released with increased success.
