These setup blocks can be used as spacers to adjust the pistons of the slave cylinders of your rim brakes so as to ensure that the brake pads will be parallel and equidistant from the surface of the rim. They have been designed to perfectly fit on the ξ /ksi/ cycling brake pads.
Here you can download the .stl file of the model and thus you can 3D print your own rim brakes setup blocks! Otherwise if you do not have access to a 3D printer and you want to get a set of these setup blocks, you can visit our official store by following this link.
