Me? Im talking about the hubshell itself ,
AFAIK, Shimano freehubs dont use a different one .
the axle is wider, and the width is added on the left end , so the hub shell is shifted to the right .
No greater base width, as the hubshell itself remains the same but the rim is over the middle of the centerline in beween those flanges
so spoke tensions are pretty close to dishless equal ..
now If you instead were fitting A Rohloff hub in the rear wheel .. then they are wider apart and a bigger diameter too ..
though 'just' a 135.. axle
in the last couple years for tandem users they added a 36 hole hubshell to make a 3 cross (maybe 4) build possible ..
people were using them in tandems and the 32 hole 2 cross did have some spoke flange cracks ,
when couples were touring to places in Peru over the Andes and such on Dirt roads carrying a full camping kit,
so they got a second hub shell option made ..
