We run 11 spd chain as do a number of tandem friends. I've mentioned this before, but the worlds top pros ride regular 11 speed chains and they don't break them. Chain strength is not the issue.

You won't be anywhere near the hoods with the extra levers. In fact, your hands will be on the narrow part of the flat bar where you have the least control and no opportunity to shift.

We have 32 spoke wheels. I have run tubeless but our current tires (Rene Herse) have very thin sidewalls and tend to constantly ooze sealant so we are running tubes.
