Mavic Simplex Downtube Shifters
#1
I need to replace repair rebuild my rear derailer shifter. It is a Mavic Simplex shifter it says RD 12.9 on the screw that attaches it to the frame. These are on a 8 speed Kestrel with a Mavic group. The shifter will not hold the gear. There is no way to tighten the shifter so that it will stay in gear.
