[Closed] 2017 Giant anyroad comax front rotor mount

I have a plan of 2 sets of wheels, and have 2 spare 180 rotors I wish to use to improve my braking, as well as compressionless cable and new inners. However I can’t work out what adaptor I need.

with the current 160 rotor on the front there is an adaptor with 180 written on it, no make,with the arrow pointing up correctly.

so I’m guessing a direct mount on the fork for the brake would use a 140 rotor.

my question is what adaptor do I need?

The forks are post mount.

please help, am I being that dull?
