At Shimano, engineers stop at nothing to make the new generation of components smarter, faster, lighter, and stronger. The new XTR SM-RT99 Freeza Rotors use the IceTech aluminum core clad in stainless steel, but take it a step further with the aluminum core flowing out into the center of the rotor in the form of Freeza cooling fins, a system that further discourages heat radiation. This means an incredible 150° of cooling with the RT99 rotor compared to a standard steel rotor...and throw in some finned brake pads; they can further reduce heat build up by another 50°. The bottom line is modulation unaffected by heat, eliminated brake fade, and fingers that stay chipper all the way down the mountain.
- IceTech aluminum core revolutionizes heat management
