  1. I have a Crescent mixte with a Dreigang (Sachs Torpedo
    3-speed--whatever you want to call it). I recently go the remains of
    a run-over bike with a Shimano roller brake. The new fork and roller
    brake are now in my mixte, but there's a problem. I like the front
    brake to have a right-hand lever. And, with a Sachs trigger shifter,
    that's rather aukward.

    Is there such a thing as a left-handed trigger shifter for the
    Dreigang?

  2. 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.

    I have used both for the internal gears on a SRAM Spectro 3x7 hub.

    My reply should have read:

    The Torpedo shifter is a small box with a thumb lever. However,
    SRAM/Sachs also made a Grip-Shift for the three speed hub.

    Yeah, you're absolutely right---I can't believe I didn't notice that.
    Now it's just a matter of cable routing.
