I usually just ask my stoker to take a look, although that obviously won't work with a blind stoker. I also have bar end shifters on the "good" tandem which give a visual clue of roughly what gear you are in. If you really want to know what gear you are in on an Ultegra or 105 STI setup, you can get an inline gear indicator for the rear derailleur cable, or a Shimano Flight Deck computer which has an electronic indicator system.
