Magic Pie Needs SOME MODIFECATION in order to make coversions more easy with out the need for spaces for the sprocket and disk and this also got the wheel more centrol this is what I did see Photo's
on the sprocket side with this mode there is no need for the 42mm washer also a 7 speed sprocket will fit now
and no need for spacers behind the disk
The only extra washer that was added was an extra inner washer on the disk side but this could be eliminated later by buy extending the round part of the axial on the disc side
