SHIMANO SLX SM-RT70-L disc rotor with a diameter of 203mm and a Center Lock mounting type.

Ice Technologies plays a key role in reducing temperature when trail conditions become more demanding.

The first upgrade for riders needing better brake performance is achieved by selecting a better combination of rotors and pads.

The larger the diameter of the rotor, the longer it takes to repeat a cycle at the same contact point with the pad.

This allows the same point of the rotor to cool better before it passes again through the friction with the pads, which will add more heat to the metal.

SHIMANO's Ice Technologies provides better and faster heat dissipation, thanks to its triple coating:

• Two outer surfaces made of steel for durability and resistance to potential abrasions.
• A third layer of aluminum, which is a good heat conductor and connects to the rotor's spokes.

The addition of aluminum significantly contributes to rapid temperature reduction, resulting in better performance throughout the braking system.
