SHIMANO Rt-Mt800 Centerlock Disc Rotor Grey, Internal Serration Lockring, 160Mm

We know that disc brakes are all that and a bag of chips thanks to their reliable all-weather braking performance, and the RT-MT800 Centerlock Disc Rotor features new technology to amp that performance up a notch. Shimano's Freeza technology means this rotor is able to cope with sustained braking and higher temperatures associated with road cycling. That advanced heat sync design reduces brake fade, and installing and removing the rotors is quick and easy thanks to Shimano's centerlock design.
