AFAIK only certain hubs can be converted to have a track axle
HB-M525 is one of them. As discussed recently, the price premium for the other one, HB-M756 is so tiny that its not really worth getting Deore when you can have XT
Might be cheaper (possibly more reliable?) to space out the bolt-on cog rather than re-dishing the wheel.
No re-dishing or sprocket spacers required for standard track chainline, bolt-on sprocket on a front hub gives 41.5mm, which is close enough. For wider chainlines, it's worth moving the whole hub sideways because that reduces the dish which is already in a front disc hub, typically down to no dish at 46mm chainline, which makes the wheel stronger.
