FWIW I had linked this thread to get opinions from the mountain bikers, and the consensus is that Monarch has screwed up on this. "Huge rotor mount? "...they have no idea. I can't imagine how many million disc hubs and mountain bike forks have been manufactured correctly according to the same standard. How many disc forks has Monarch put out there? The dropouts really need to be flush to the inside of the fork leg instead of centered. Question...are the fork legs spaced to 100mm inside to inside where they mount at the crown?
