A cool innovation.

Shimano's SM-RT81 Ice-Tech Disc Rotors feature a unique 3-layer construction that allows them to operate up to 220 degrees (F) cooler than standard steel rotors. They're built with aluminum core and two stainless steel outer layers to lower the operating temperature, resist power fade and increase pad life. Optimized for Ice-Tech brake pads. Shimano Center Lock compatible. Available in 160mm and 180mm sizes. Actual weight: 123g (160mm, hardware included). Sold individually.

These Are Excellent Discs

I love these discs. I replaced the Stock Tektros on my Trek FXS6. I put Shimano resin pads on too. I'll be further upgrading to Shimano XT calipers and levers. It'll be a sweet set up! .

These are the rcommended rotors to use with Shimano brakes
by Lastostrogoth

There are well made, easy to install, and are the rotors which Shimano says are the only ones that should be used with their Ice Tech brake set. They are well made and quiet.

Best performing rotor for the money
by brooksdarg

As is true for other XT components, this rotor defines the intersection of superior performance at a reasonable cost. Excellent stopping power in all conditions. The only caveat is that one must be careful when truing these rotors - they can be irrevocably damaged if bent too far.

Great product, fair price, and quickly delivered.
by Brainbow

For daily use and for high-mileage randonneuring, these rotors deliver confident stopping power on demand. Paired with semi-metallic pads for all-weather predictability. Would replace with same when worn out.

Supreme stopping power
by digita6

I replaced my stock TRP rotors with these, and despite the (slight) weight penalty, they stay true and have incredible stopping power. I'm sticking with Ice Tech and not looking back.
