The owner the Halutz bike shop in Ber-Sheva was glad to find someone interested in an old broken down Huret Duopar derailleur in his "can't bare to throw away" box.
The hanger and parallelogram are fine but the spring and possibly the cage are not.
Does anyone have a scan of the brochure that came with the Duopar? Does anyone have experience maintaining these little beauties?
