Shimano SLX SM-RT70 disc brake rotors deliver powerful and consistent brake performance for all riding conditions. The ICE TECHNOLOGIES rotor significantly reduces heat build-up in the brake system to ensure consistent high performance braking even on the steepest downhill stretches. Shimano's center-lock mounting system makes installing and removing rotors quick and easy thanks to the spine mount and lock ring design.

  • Aluminum spider
  • Includes lock ring with external serration

Richard H. ★★★★★

Even after a long descent, the brakes felt consistent with no fade thanks to that ICE Technologies heat reduction. Mounting was straightforward and they've been silent so far, which is more than I can say for the last set.

Benjamin ★★★★★

Installed these rotors and noticed the difference right away on a long descent—brakes stayed consistent even when things got hot. The heat reduction really works, and they've been silent with no warping so far.
