Steamer hit the nail on the head. It is the recumbents comfort that always comes to the fore. More and more long distance riders are turning to bents. While almost anyone can stand the seat of a DF for short rides, when it comes to day long rides, or touring day after day the bent shines. Also another advantage of bents is that almost all "on board" energy can be directed to the legs. Since that the upper body doesnt need to be supported by hands arms and shoulders no energy is used there.
