This design places the hose outlet as close to the rotor as possible for ideal performance. Measure your hat/rotor offset before ordering:
The duct face is 44mm back from the hub face (the surface with the wheels studs in it where the rotor hat contacts), measure from the inside surface of your rotor hat to the rear friction surface of the rotor. If it’s less than 44mm, it will clear!
