SHIMANO SLX SM-RT76-S disc brake rotor with a diameter of 160mm and a 6-bolt mounting type.

The 6 black aluminum spokes maintain the shape of the disc rotor and prevent distortions caused by rising temperatures.

The first upgrade for riders who need better braking performance is selecting a better combination of rotors and pads.

The larger the diameter of the disc, the longer it takes to repeat a cycle at the same contact point with the pad. This way, the same point of the disc has time to cool better before passing again through the friction with the pads, which will add more heat to the metal.

Additionally, the metal technology used by SHIMANO in their high-quality brake series allows compatibility with metal pads that maintain their performance at high temperatures.
