The clad steel / alloy / steel rotor construction allows heat generated from braking to radiate quickly through the aluminum core achieving surface temperature drops of around 50 deg C. When used with Ice-Tec pads surface temperatures can drop from around 400 to 300 deg C, this provides great improvements in performance all round.
You know, you probably need pads too. Keep your Shimano rotors performing like new with genuine Shimano Ice Tech disc brake pads here.
If you must use a six bolt hub, then this is a very good option.
I upgraded my Scott Genius from Avid Elixirs to Shimano XT brakes front and rear with 180 mm Ice-Tech rotors and what an improvement! First, no more squeaks and squeals as I had with the Elixir pads and rotors. In addition, my Ice Tech rotors never faded or overheated on a 6 day epic ride from Chamonix to Zermatt while you could smell the other guys' rotors and pads burning! Ice Tech rotors really keep their cool. I've used them for 3 years now in Fort William, Morzine, Dolomites, Morocco, Zermatt, Chamonix and they haven't failed me yet!
I have been running these on my Epic Comp 29er for 3 months now and have not experienced brake fade. I was having an issue with break fade and these resolved my issue completely. Great buy!!
I have this Shimano 203 mm rotor on the front, and I love it, quiet with great stopping power, I plan on replacing the back with this rotor as well.
I have a 180 rotor in the front and and a 160 rotor in the rear. While I have lower end Shimano brakes on my HT and Tektros on my 26", neither compare to the phenomenal braking these rotors give me paired with XT brakes on my new trail bike.
Quiet, strong, and stays true. These 2 pc rotors are a perfect match for the Shimano M-785 XT brakes.
Been using the same XT rotors for two years In all weather with no issues at all. Best brake system ever, bar none! Price Point rocks!
It's all in the rotors. Ice tech make a big difference in braking power.
I order a 203 and 180 to go with the Shimano XT M785, good setup I must say. great heat dissipation and they do not squeak. I would of given it 5 stars but the 180 rotor was not true straight out of the box. But overall awesome rotors!
I was able to reduce my cross country bikes rotor size from SRAM 185mm down to these Shimano rotors in 160mm. The heat dissipation is fantastic. They runs silent and stay true. Great brakes!
I added these (180/Front, 160/Rear) as a replacement for my Avid Elixir CR brakes. What an improvement !! No squeals or groans !! This was part of an overall upgrade with the 785 XT brakes One thing to note - the installation instructions from Shimano are outdated. These rotors no longer ship with the lock ring as the instructions indicate. Instead, use the tabs and bolts that are included and bend the tabs up when complete. Recommended !!
