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.
At Sigma Sports you'll find disc brake rotors available in various sizes, with road bikes generally using 140mm or 160mm rotors, while MTB models start with a minimum of 160mm rotors. With brake rotors also geared towards gravel bikes and premium component brands in stock such as SRAM and Shimano, you will be able to source the perfect stopping solution.
