Is there any reason I can't use a road/mtb rear disc hub to use a bolt on fixed cog, and then in future use the other side to fit gears?
Chainline for a bolt-on sprocket on a 135mm OLN rear hub comes out at 54mm.That's too far out to work nicely with a road chainset, which will typically have the outer ring at about 47mm. The middle ring of an MTB triple is typically at about 51-52mm, which is close enough.

Thanks guys, this is pretty interesting. Especially as One-one have a SS MTB crankset on ridiculous offer. Am I right in thinking a SS MTB crankset would run about the middle ring of a triple?
