The Shimano SM-RT99 Freeza Centerlock rotor is the pinnacle of Shimano's ICE Technology development. First featured in Pro Downhill mountain bike racing, the line has been expanded to include all sizes of rotors so other disciplines can too can enjoy the benefits of this top-of-the-line brake technology. The RT99 features Ice-Tech technology which is Shimano’s best-in-category heat management system. Brake heat from long descents sucks power from your brakes, but not with this rotor. The heavily shaped, lightweight Freeza rotor sheds heat incredibly fast for optimal performance, even in the most demanding conditions. A cooler rotor means more braking power, and more consistent braking performance, so you can forget about your brakes and focus on your riding.

The RT99 rotor with its additional cooling fins radiates significantly more heat than the already remarkable RT98. The benefit to you? when used in conjunction with other Ice-Tech technologies such as Shimano's finned disc brake pads and mineral oil brake systems, you can even go down one full rotor size to save weight without any decrease in cooling performance!

  • 20% increase in stopping power
  • 20% longer pad life
  • Additional 50 degrees Celsius decrease in operating temperatures over previous Ice Technology rotor
  • Package includes one rotor and a Centerlock rotor lockring
  • 203mm Weight = 173g, no lockring

      Comments about Shimano RT99 Ice Tech Rotor:

      Light rotors that look great but are pricey. If you are installing with the avid bb7 disk brakes you need to bend back the metal spokes on top of the brake pads or it will not fit properly...the cooling fins will hit the metal... Bend back and problem solved.
