I have an old Mk1 Fargo which i’ve just powdercoated as it’s had a hard life and am rebuilding at the moment. Would love a new one with the alternator plates and ability to take larger tyres, but have watched for frame and forks go up from £549 to £900 over the last few years.
Great bikes and easy to ride all day on, trouble is not many second hand ones knocking about.
A lot of people have put drop bars on Surly Ogre/ ECR, the Singular Swift and on On One Inbreads if you search interweb.
This guys blog has page after page of info on drop bar mountain bikes, first page is here:
