0.3g Lightweight Brake Calipers GRK 4 pieces The mounting position is slotted for adjustment, preventing interference with the wheels. Please check the size in the photos. They are white, so you can use your favorite color of paint. I have painted them with Tamiya polycarbonate fluorescent spray. Made with a 3D printer and a lightweight structure, please be careful as they may break if excessive force is applied. I also use them, and I think there are no problems with normal use.
