I haven't seen the Torpedo shifter. Carefully reading your post, I infer you
have the Driegang with coaster brake (back-pedaling brake) and that this is
why, with the right hand hand brake, there is a problem.
The shifter for my Sturmey-Archer 3 speed hub was made of two metal plates
riveted together with the latching mechanism between. Is the Torpedo shifter a
grip-shift type?
I used to mount my S-A shifter in various places on my narrow tube frame bike.
I even had it behind the seat on the narrow seat post once! It was symmetrical.
Can you describe the Torpedo shifter more fully? Can you direct us to a web
page with a picture of it? If it is symmetrical like the S-A it could be
mounted on the right side. If it's a grip shifter, reversing it would be hard.
But don't grip shifters usually allow room for a brake?
I think you're stuck with a left hand brake for now, but internationally, right
hand braking is more common, so by searching worldwide, you may find the left
hand shifter.
