The Carrera felt very nice, not sure how much the carbon fork and aluminum tires contributed to that or not. Any thoughts about the Speedhub vs. the Ultegra w/ DI2 for tandems?
What would you go for?

It depends on what you mean by "trails". If you're riding on flat gravel in dry weather, the Speedhub has more drawbacks (weight, price, bigger gear jumps) than advantages (low maintenance, reliability). The Speedhub is more useful for touring in rough terrain and wet weather.
If you like to Century rides at a fast pace, then Di2 is the way to go. It's lighter than Speedhub with far more precise shifting.
