And what value did this comment add to the discussion? Or was this just to show off your (supposed) superiority?
I'll bet that there are not many people who have tried DI2 on a tandem. I happen to be one of the few people who have tried Roholff on a tandem, however. With a derailleur system, whether cable-operated or electonic, the rear wheel still takes a partial revolution to move the chain from one cog to the other. With the Rohloff, this is not a factor and shifts can occur quicker than a derailleur.
