As a W.V. is 126 mm from the factory I would just put the wheel in to test, it if sanafactory then spread the frame, no need to do anything with brake bridge. Things to be aware of , you may need to adda 1/2 or 1 mm washer to the drive side axel, its tight. A 114 link chain will work with 52/34 but your mechanic might want to add a link or two. Good luck on your project World Voyageurs are great bikes
