Shimano RT-MT800-SS Disc Rotor

The FREEZA technology features an integrated heat sink design that significantly increases surface area. This allows the rotor to dissipate heat much faster than standard designs, which prevents brake fade and maintains consistent stopping power on long, technical descents.

Yes, the RT-MT800-SS is fully compatible with both metal and resin brake pads. This gives you the flexibility to choose the pad compound that best suits your riding style and local trail conditions.

Yes, this rotor uses the Shimano Center-Lock mounting standard. It utilizes a spline mount system and a lock ring, which makes installation and removal much faster and more secure than traditional six-bolt rotors.

A 140mm rotor is typically best suited for lightweight riders, road bikes, or cross-country setups where weight savings are prioritized over maximum heat capacity. If you are a heavier rider or frequently tackle steep, sustained descents, you may want to consider a larger diameter rotor for better heat management.

The two-piece design separates the braking surface from the carrier, which helps manage thermal expansion. This construction reduces the likelihood of the rotor warping under intense heat, ensuring a smoother and more reliable braking feel.
