Thanks for that, but DAMN. Not the same as the 990 which is about 143mm. Back to the drawing board. Maybe if I start with a 690 enduro hub. Hmmm...

EDIT: OK, after a bit more checking it looks like the 950/990 adventure, the 950 super enduro, and the 690 enduro all use the larger 143mm rotor bolt pattern. While the 950/990 adventure use the larger 30mm, the super enduro and 690 enduro use the same 26mm axle as the RFS model. I might have to start with a 690 enduro or 950 superenduro front hub. I'll also need a different caliper holder if not an entirely different caliper.

Measurements ripped off of metalgear's website:

Metalgear makes some nice rotors at pretty reasonable prices too:
