Disc brake rotor Shimano XT/Ultegra RT-MT800 160MM Ice-Tech Freeza CL Int. Magnet

SHIMANO's DEORE XT RT-RT800 compact and lightweight disc brake rotors feature rapid heat dissipation thanks to ICE TECHNOLOGIES FREEZA heat management system. Installing and removing the rotors is quick and easy with SHIMANO's CENTER LOCK design. This is a version has integrated magnet for use with the STePS EW-SS302 speed sensor on E-bikes (SENSOR NOT INCLUDED)Advanced heat sync design reduces brake fade New disc brake rotor construction boosts heat dissipation and reduces fade ICE TECHNOLOGIES FREEZA Easy disc brake rotor installation with spline mount and lock ring CENTER LOCK Weight: 132 gAlloy lock ringOutside diameter: 160 mm Pad material compatibility: Metal and ResinTECHNOLOGIESICE TECHNOLOGIES combined with FREEZA disc brake rotor construction rapidly dissipates heat for more consistent braking performance in extreme conditions, longer pad life, and less brake fade and noise. Lightweight clad rotors with heat dissipating paint on exposed aluminum layer segments provide superior cooling, consistent brake performance, and lighter operation under all conditions. Clad brake rotors with Aluminum/Stainless fins support rapid heat dissipation which helps reduce maintenance, provide longer pad life, and create less brake fade and noise. CENTER LOCKThe 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.
