For superb stopping power in all conditions, Shimano Ultegra SM-RT800 disc brake rotors deliver consistent braking performance thanks to the Iice Technologies Freeza construction.
With better heat management, the SM-RT800 rotors withstand brake fade on long downhill stretches and provide substantially quieter braking. Shimano's Center Lock mounting system makes installing and removing rotors quick and easy with the spine mount and lock ring design.
Center Lock - The Center Lock system makes an easy rotor installation possible with spline mount and a lock ring. The lock ring mounting system reduces the total working hours by shortening the amount of time of both installation and de-installation. In addition, the secure fixing by the spline mount enhances precision and rigidity while improving braking efficiency.
Ice Technologies - The fade, which can occur to disc brake rotor and pad when braking on a long downhill ride for instance, has a negative impact on the braking performance. Shimano has adopted Ice Technologies disc brake rotor and Ice Technologies pad to realize the cooling technology for consistent performance. The clad disc brake rotor blade, which has a 3 layer-sandwich structure of stainless steel, aluminum and stainless steel, provides better radiation performance achieving from 400˚C to 300˚C surface temperature. Also, the radiation fin has been adopted for the pad. Moreover, the clad disc brake rotor blade and the radiator fin provide long pad life, less noise, less fade and lightweight.
