I am thinking about upgrading our mountain tandem frame to a lighter one with a 145mm rear spacing. I would really like to continue to use the same wheels that we are now using which have a 135mm rear hub.
The question that I have is will I need to redish the wheel to keep it centered in the frame and make up the additional 10mm on the left with a axle spacer? The disc brake setup should not be a problem as I can turn a spacer on the lathe.
