XT 785 brakes + IceTech finned pads + SLX sm-rt66 (or rt76)* rotors, as for my opinion, is the best brakes combo for performance\cost eliability ratio applied to an XC, AM or Trail bike. Worked flawlessly for years from ice&snow -10*C to sand&dust +40*C.
Didnt even mention why the sandwich structure is there. "there is only 2 differences in my mind, the weigth and the different braking surface" Totally backwards. The braking surface is the same in both, its steel. The alluminium in the middle is to improve heat dissipation, the weigth saving is a side-effect bonus from using aluminium, not the key point.
I bought the SLX SM-RT66 rotors when I got my XT brakes. They weigh only 113 grams for the 160mms, and they cost a fraction of the XTs. It's a little hilly here in the Rockies, and at the bottom of a 2 mile 1,500 vertical foot descent I get no fade in power. I can lock up effortlessly with one finger (I'm 150 pounds which probably helps). And, they're very quiet with metallic pads. I won't spend more next time, since I see no benefit to the more expensive rotors.
My rear 180mm Ice Tech kept going out of true every other ride........ True it up and have no brake rub and by the end of the 2nd ride there was the tick-tick of brake rub again.. Switched to a 180mm RT 76 and haven't had a single issue in almost 500 miles. Something with the aluminum center is my guess.
Its 2020 and i still got more information with this video. Keep it up. Im looking for replacement of my 160 shimano brake rotor. 200mm is good without ice tech?
HI there, 1st of all i must say that your videos are great,2nd ty for them because i learned some new things i didnt know before. Just one question, is there any chance that you compare and test XT brakes vs SLX?
I've had both with Shimano saint breaks. I find the ice tech to fragile. The aluminium core is too soft. I grazed a stump and it bent like butter on my first ride. I reverted to the 76 that has only steel and it is much more resistant. I put them trough hell and they've always come back. Maybe I was unlucky
Even though this is an older upload it still has great info . One question . Can the one piece 6 bolt rotors be interchanged with the two piece 6 bolt rotor without affecting alignment ?
is ther any different widths of the rotors 160 6 bolt can't get the wheel to run between the discs even with the cable and inside adjustment backed right off
do they help enough with heat dissipation for you to notice a difference on steep descents? brake performance falls off a cliff when they heat up too much.
@@LoveMTB slx has ice tach but not freeza tech. But I think the brake effect will be much better. My friend has deore brakes + slx rotor and it´s much better then mine xt+deore rotor
@@LoveMTB If the rear disc temps remain higher I would suggest placing the Ice Tech disc in the FRONT with the solid steel RT76 in the rear. I also tend to ride the rear brake to control speed since flying over the handlebars is not my idea of a good ride. Many users report the Ice Tech rotors go out of round easily. RT86 Front/RT76 rear would provide the most RELIABILTY which is more important considering there’s not a discernible difference in performance between the two types of rotors. I was forced to buy one of each due to low stock everywhere. One RT76 180mm appeared on Jensen and I made the decision to but one of each. I’m still waiting for Jensen to cancel my order claiming the disc was in stock out of error.

Actually, the 86 has slightly but noticeably larger braking surface.
They are actually both XT Rotors. The only difference is the aluminum core vs. full steel.

I have those in 160 and I would not recommend them in 180. They get out of true very easily.
i have rt 76 180mm at front and i need to true it every single time i come back from a ride. at price of 40$ they are not good at all.

Many thanks!
brilliant video thank you

***** ty :)
I'd like to know what the depth of the braking surface is on the rt86. The area that the pad contacts looks like it has about 2mm extra on the rt86.
For me the old RT76 is better than new one Ice Tech.

THanks for the input! I was feeling a little jelly about the aluminum rt but after reading this feel much better about the XT...Thank You!
got a slx brake with xt ice tech rotors i love it

That was exactually what I was asking . thank you

Both the RT76 and RT86 are XT rotors, the RT86 adds the ice technology.
8 is xt series
7 is slx series, so rt86 is xt, and rt76 is sls
Rt86 is actually the XT. I’ve owned about 3 pairs of these rotors, and the box does say XT.
any improvements in braking performance on the ice techs?
do they help enough with heat dissipation for you to notice a difference on steep descents? brake performance falls off a cliff when they heat up too much.
I have SHIMANO XT BL-M8100 and deore rotors, I am going to upgrade rotors for slx ice. Will it be better or not.
@@LoveMTB slx has ice tach but not freeza tech. But I think the brake effect will be much better. My friend has deore brakes + slx rotor and it´s much better then mine xt+deore rotor
My only grief is when you compare weight `s ....you weigh a well used disc against a brand new one ....but I love the XT RT 76
RT76 is the IceTech version of the SLX RT66. RT86 is XT. Both are Icetech
i have a question. i happen to have one of each rotor, both in 160mm. where should i put the ice tech one, in the front or in the rear?
@@LoveMTB thanks a lot! great content!

Better heat control with the ice tech version.
I can touch ice tech rotor surface after long braking downhill compare other rotors. You have to demonstrate the heat dissipation i think.
What is the minimum thickness for the Ice-tech rotor?
