Description

Less Heat + More Stopping Power = Better Braking

Shimano Ultegra RT-MT800s are compact and lightweight disc brake rotors that feature rapid heat dissipation thanks to Ice Technologies FREEZA heat management system. Installation and removal is quick and easy with Shimano's centerlock design.

Shimano's Ice Tech Freeza technology means this rotor is able to cope with sustained braking and high temperatures. Shimano's advanced Freeza heat-dissipating design reduces brake fade.

Internal Lockrings install with a cassette tool and fit most 12mm thru axles. External lockrings install with a bottom bracket tool and fit all axles up to 20mm.

Features:

  • Ultegra series disc rotor for reliable stopping power in all conditions
  • Maximum heat dissipation thanks to Ice-Tech Freeza technology
  • Available in 140 or 160mm sizes
  • Available in internally or externally splined versions
  • Centerlock hub compatible
  • For use with road, CX, or gravel disc brake systems

bought these to put on a backup set of wheels so I did not have to swap rotors each time I was changing wheelsets. these seem like a good value especially when they were on sale on a deal of the day special. I wonder if anyone has received $50 for submitting a review.....

These rotors are really nicely built, they look very nice and I never worry about the rotor failing to stop me. they last a long time. I have used these since they came out and have never had any issues with them.
