I'm the OP on this thread, I just looked at my original post - I should have gone with my instincts and stuck with drops, sad to say, though my dissatisfaction with the flat bar setup only emerged on a long tour in East Tibet - comfort becomes almost the ONLY thing when you do 8-10 hour days in hard conditions like that. Around town, the Raven's been great, of course, and I had no complaints on an earlier tour in summer holiday conditions on Germany's Baltic coast. But grinding up long passes in China, I spent far too much time in the noisy lower gears of the Rohloff.
At this point I don't know whether to shell out for a cheaper drop bar bike such as Dawes' Ultra/Super/bog-standard Galaxy in addition, or part company with the Raven to fund that. I think my days of touring off-road are close to an end, so I would like to go back to that smooth drop bar touring bike feeling rather than the 'expedition' bike I opted for.
