Shimano RT-CL800 Ice Tech FREEZA Rotor with Internal Lockring 140mm Silver/Black

With quieter control for any terrain the Shimano RT-CL800 Ice Tech FREEZA Rotor with Internal Lockring has a focus on decreasing disc brake rotor heat deformation, the result of the new disc brake rotor is quieter than ever brake performance without sacrificing weight or heat dissipation.Shimano RT-CL800 Ice Tech FREEZA Rotor with Internal Lockring Highlights-Ultegra grade RT-CL800 Ice Tech rotors give excellent performance made from a stainless steel / alloy 3-layer sandwich construction that manages heat while ridingThe 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 deg C. When used with Ice Tech pads surface temperatures can drop from around 400 to 300 deg C, this provides great improvements in performance all roundIce Tech rotors achieve long pad life, less noise and less fade due to improved heat dispersionUsing the proven Shimano Centre Lock system for excellent rigidity and security with an easy set-upRotor contact surface has been developed for excellent pad clearing and cooling which increases pad performance and lifeLarge forged alloy spider supports rotor surface, increasing rigidity and reducing weightComes complete with alloy lockring
