Frame: Seaboard CX03

Brakes: Ltwoo R9 Hydraulic

These brakes came with rear adapters for 140mm and 160mm brakes.

I installed the 160 adapter and a 160 rotor. But the pads now do not sit flush with the rotor braking surface and I cannot eliminate the rubbing..

The 140mm adapter would only make it worse from my understanding.

Is it just a matter of only a 140mm rotor being able to fit to my frame with this groupset?
