On my Caad12 disc I ran 140mm front rotor with post mount, no adaptor.
Seeing as I've installed your old brakes on my fork and frame it means they're installed without an adapter. The fact that they clear and can handle the 160mm rotor means it can't be a 140mm forks as Hongfu claim.
Weird, I've put 160 on the front of mine, no adapter
