    Mavic Simplex downtube shifters

    I need a right side (rear derailer) downtube shifter for my kestrel roadbike. The shifter is broken and will not hold in gear. I believe that it is a Mavic Simplex shifter. it says RD 12.9 on the bolt that tightens the shifter to the frame. I will take a set if available.
