Now that we've racked a few miles on our new tandem my list of learning points has gotten reasonable small, but one of my most troubling things as captian is being decoupling from the drive train. I can no longer look down to see the front derailer alignment, nor hear when something is amiss at the cassette all the way in the back. To make things worse my stoker has never been really tuned-in to the drive train even on her single, and I'm forever saying, do you hear something? Thankfully the shifters have indicators that give me an idea of the relative position of the front derailer and the indexing on the rear has been spot-on.
So my question is has anyone devised a system to get good feedback from your stoker about the drive train?
