Shimano has enhanced their already top - notch Ice - Technologies Freeza brake rotors. These rotors come in four sizes, all lighter in weight and with improved heat dissipation. They offer reliable, fade - free braking on any terrain. Ideal for riders of all disciplines, especially XC, Trail, Enduro, and DH riders seeking high - end Centerlock mounting rotors. Mounted using the Shimano Centerlock standard, they're made of stainless steel and aluminium. You can use either metal (sintered) or resin (organic) brake pads. The 'stainless steel - aluminium - stainless steel' floating rotor construction is a game - changer for heat dissipation, with up to 20°C improvement in the 203 and 180mm discs compared to the previous Ice Technologies Freeza ones. The 160mm rotor weighs 109g. Each box includes one Shimano XT RT - MT800 brake rotor and a lock ring. Pros include consistent braking, excellent heat dissipation, and being lightweight yet stiff. However, they're not compatible with 6 - bolt hubs; you need Centerlock hubs to use them.

Using your Shimano XT RT - MT800 brake rotor is straightforward. First, make sure you have a Centerlock hub, as these rotors won't work with 6 - bolt hubs. Install the rotor onto the hub using the provided lock ring. You can choose either metal (sintered) or resin (organic) brake pads according to your preference. When riding, enjoy the consistent and fade - free braking performance on any terrain. As for maintenance, regularly clean the rotor with a mild cleaner to keep it free from dirt and debris. Check the rotor for any signs of wear or damage, like warping or excessive thinning. If you notice any issues, it's a good idea to replace the rotor. Also, make sure the lock ring is tightened properly before each ride to ensure safety.
