I need to rig something that will allow the right brake lever to pull both brakes on a Shimano 9 indexed shifter.
I did it once by soldering a "Y" in non-stainless cables a few inces down the bar from the lever and run through a piece of hollow rectangular bar stock. Problem was, in Florida, the cable rusted very quickly (bare cable running under top tube through guides).
I suppose I could use Stainless and take it somewhere to be welded or "silver soldered" but then every time I want to change cables, I have to start all over again.
Anybody have a good idea? I know they make a useable, in reverse, rig for tandems,allowing either rider to brake, but it's bulky and ugly!
