Shimano SM-RT86M2 Ice-Tech brake disc, XT, diameter 180 mm, 6-hole mount, Aluminium, Black

Great product never disappointed with XT.

6 months of riding just love it, yes the ICE works it stays cool, getting some for wifeee

As described. Fast shipping. I'm happy with this purchase

I have a decent size e-bike and I like Shimano I used to use it on my specialized in these discs are rated for any bike so far I've used it and haven't had any issues and it hasn't worked on me and I have like my front one uses more break I think I got the design there's two designs but either way this was a legit purchase to change for my brakes and I will definitely use again I have the 180 mm

Decided to upgrade my MTB & decided the brake systems was a good place to start. I upgraded from V-brakes to discs.I purchased a pair of 180mm SHIMANO XT SM-RT86 Rotors, pair of Shimano M375 calipers, a Shimano SM-MA90 post to post adapter (front), a Shimano SM-MA-R180 IS to post adapter (rear) & new cables. This setup works awesome, strong breaking, even when wet (much better than wet V-brakes).These SHIMANO XT SM-RT86 Rotors did not come in the Shimano packaging, nor did they come w/any installation instructions. They did come w/mounting bolts (w/pre applied thread locker & tightening plates (see pic). From what I can tell from the branding, fit & finish, I believe these are OEM parts. I am fine w/that, it saves me money w/out sacrificing quality, especially w/something as important as stopping.According to Shimano’s website, the weights for their XT SM-RT86 rotors are as follows:160mm-131g | 180mm-152g | 203mm-187g. The lighter weight is due to an aluminum core sandwiched between steel. This is also supposed to allow for quicker heat dissipation. What I know is that they work really well.If you’re in the market for disc rotors & your hubs are 6-bolt not center mount, I can confidently recommend Shimano CT SM-RT86 rotors. If you’re on the fence about upgrading your brakes to disc brakes, I’d say do it. Discs stop much better than V-brakes, they look great & if your thinking about upgrading your fork in the future, you’ll definitely have more options to choose from w/disc brakes than w/V-brakes.Thank you for taking the time to read my review. I hope you found it helpful.

Great upgrade.

I recently bought a 2015 Specialized AWOL Elite, which comes with 160mm rotors and Tekro Spyre mechanical disc brakes. The rear brake caliper mounting posts needed facing (they were crooked relative to the axel). Since my local bike shop couldn't initially find a Park DT-4 or DT-5 Facing Tool, I decided to fix it myself (and upgrade to 180mm brakes) using:1. These 180mm IceTech rotors2. Avid 20 S Post Spacer Set, Front 180/Rear 160 2 sets needed, 1 for front, 1 for rear.The AVID spacer set includes rounded washers that allow adjusting the caliper angle, and compensating for the angled mounting posts. But, after I ordered the rotors and spacers, the bike shop lead mechanic came back from vacation and pulled the facing tool out of a drawer. Now the caliper posts are square to the axle. I went ahead and installed the 180mm rotors and caliper spacers.The 180mm rotors are a noticable improvement in braking performance, and look very sharp on the bike. Overall, it was a worthwhile upgrade.
