I guess with the bike industry being so weight obsessed with its parts, even a 10 to 20 gram saving per wheel would probably inspire the creation of a new standard.
Varies by hub maker. Onyx Racing Products makes glorious hubs MUSA --however their QR/12x100 "CX/road" hubset is specific from their QR/12x100/15x100/15x110mm part
Road/CX

MTB

Claimed manufacturer weight difference between the two 75 grams. Now how much of that difference is sheer MTB "over-building versus road/CX, and how much is just due to the larger axle...I don't know.
I have a set of Onyx hubs laced up. Very ginchy. But because the carbon fork I wanted only had 15x100 TA (if you want a carbon fork, disc brake, with rack mounts-there aren't many choices), I had to get the Onyx MTB hubset.
