Sort of off topic, do you guys like these flight deck computers when they're working properly? I would really like to have one on my tandem to show what gear I am in. I can't rely on my stoker to tell me, she's just too inexperienced riding bikes. The times she has tried to look, she threw us off balance and I don't really care to repeat that experience. And of course I am way more accustomed to riding singles where I just look down if there's any question about what gear I am in.
