Just built up my new Surly Straggler for commuting. Used the old wheelset, which has Nexus 8 IGH at rear and Shimano Dynohub at front, from my old Norco CityGlide. The wheels also use Shimano rollerbrakes, which I upgraded from the original set. Between the IGH and the rollerbrakes, the drivetrain is totally all-weather - including winter riding in snow - and virtually maintenance free. Since pic's I've also swapped handlebar for a Trekking bar which I'm going to try out.
Nice ride! What type of rear rack is that, and has it been modified?
