Disc brake rotors provide the crucial braking surface for disc brakes on your bike. Like any other braking system component, they need replacement once they wear out. Disc brake rotors are typically constructed from steel and often feature a two-piece design with an alloy 'spider' in the centre. This design is especially useful on road bikes, as it helps maintain rotor alignment while reducing overall weight.
