Shimano RT-CL800 Ultegra Ice Tech FREEZA Centre Lock Rotor

Ultegra grade RT-CL800 Ice Tech rotors give excellent performance made from a stainless steel / alloy 3-layer sandwich construction that manages heat while riding

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 degree C. When used with Ice Tech pads surface temperatures can drop from around 400 to 300 degree 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 Centre 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
Comes complete with alloy lockring

With 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.
