Yeah, All SRAM or shimano or anything hyperglide that isn't trying work for campag is the same spacing as far as speeds go, MTB or road, 10 speed takes up less space because the gaps are smaller, there were a few only 10 speed freehubs that won't take anything else and 11 speed road needs a longer freehub body, MTB fits on an 8/9/10 freehub as it overhangs the base of it a little, spacing is still the same though so they work between road and MTB still.
