A Salsa Fargo frame is on its way from the US. I ordered it through Foxcomp Turku and it should be here in sometimes in the beginning of January. My Nishiki Bigfoot will be retired, at least temporarily, and donate the wheels and drive train to the Fargo. An On-One Midge offroad drop bar is already ordered, but I still don't know which shifters to get. The most likely alternative is the Tiagra 9-speed STI shifters, since I'm not convinced that barend shifters would be good enough. The Fargo should serve me well as a general purpose bike for commuting, cyclocross rides as well as some forest road and terrain touring.
For more info about what the Salsa Fargo is used for, see this video and the Go Fargo and Gnat likes blogs. My ambition level is somewhat lower, though.
