Looking for the correct adapter to install Shimano GRX brake calipers to post mounts front and rear with 160mm rotors.
Found Cinq adapters which are nearly as expensive as the brake calipers
Is this the cheapest/only way to do it ?

Yep - that's basically the answer.

Alternatively and just as expensive, remove and sell the caliper and fit Hope?

or some regular shimano post mount calipers. Pre flat mount, thats all the ultegra level kit was.
