Hey Rocco,

In order to get the correct replacement parts for your disc brake assemblies we'll first need to identify what brand/model you have. Manufacturers like to make their parts just slightly different so that they won't work with other brands and once you get into the 8k capacity range things start to get extremely specific. You might have AL-KO axles but some other brand for the disc brake assembly so you'll want to check your current calipers for the number stamped into the back of them so we can figure out what you have.
