I'm a "newbie", so hope I post this question clearly. We just bought a used tandem TT, it comes with a mirror, but it is in the back, doesn't do the stoker ( or me) much good, since he is blind. I don't know how I could adapt it to use in the front, because my shifter in on the top of my OSS stalk. (or is is called a handle??) Without thinking I bought a mirror that fits on a DF, not gonna work with the TT. I need mirrors that work for me. Any suggestions?
