I am using a 6 bolt cog on a rear hub, xt m756, converted to solid axle courtesy of velosolo. 135mm OLD. Chainline is ok but not perfect with 113mm BB and sugino rd2 cranks on the outer chainring position. I'm also considering converting a front hub because then I could get the chainline perfect but would be running 3/16 balls on the rear. It was trivial to bolt the sprocket on the existing hub though versus building a new wheel.
