what is the chainline of 6 bolt mounted cog on a disc hub?

For unmodified front hubs, the mounting face is 40mm for normal hubs (100×9/12/15 and 110×20) and 45mm for Boost (110×15). Assuming 3mm thick sprockets that gives a chainline of 41.5mm or 46.5mm

IIRC, the mounting face on 135mm rear hubs is 50mm, so that would give a 51.5mm chainline

it varies a bit from brand to brand but most are ~15mm in from the chainstay: so ~52.5mm mounting face and 54mm chainline

54mm chainline

Yeah, 50% maths fail by me and 50% not remembering what the offset from the dropout was. I think you're right
