Sitting at Ultegra / XT level in Shimano’s hierarchy, the RT-MT800 Internal Lockring Ice Tech Center Lock Disc Brake Rotor is designed to dissipate heat as much as possible for better, more consistent braking performance.

The rotor is made from a 3-layer sandwich of stainless steel and alloy which helps spread the heat out away from the braking surface, reducing the temperature by as much as 25%. This temperature reduction prevents the heat build-up that can cause brake fade and inconsistent power and the surface design of the rotor also helps with cooling and aids pad longevity.

 

• Shimano’s Center Lock mounting system is simple and safe, providing good rigidity and security, (No Lock Ring Supplied.)
• Deore XT and Ultegra grade RT-MT800 Ice Tech rotors give excellent performance
• The clad steel / alloy / steel rotor construction allows heat generated from braking to radiate quickly through the aluminium core achieving surface temperature drops of around 50°C. When used with Ice Tech pads surface temperatures can drop from around 400 to 300°C, this provides great improvements in performance all round
• Ice Tech rotors achieve long pad life, less noise and less fade due to improved heat dispersion
• Using the proven Shimano Center Lock system for excellent rigidity and security with an easy set-up
• Rotor contact surface has been developed for excellent pad clearing and cooling which increases pad performance and life
• Large forged alloy spider supports rotor surface, increasing rigidity and reducing weight
  
• Diameter: 140mm, 180mm, 203mm
  
• Mount: Centre lock
