Broken Sturmey-Archer dual cable 5-speed shifter I have this Sturmey-Archer shifter which controls a hub with 5 speeds with cables on both sides of the hub. These 5 speed with 2 cable shifters are very hard to find and my shifter broke as the picture shows. Because only the brace of the shifter broke I was wondering if I can buy just that part or what would be the best way to still use this shifter.
It looks like these are mounted in the same way as downtube shifters. If that is so, many downtube shifter band clamps are available aftermarket for the frame, stem or handlebar. If you take the shifters off your clamp you should be able to compare photos of this type of solution
