Reviews over the

Shimano XT M8100 RT-MT800

This brake disc is perfect for good braking action without suffering from heat. They brake well right away but after braking in, they do even better. Highly recommended.

Pros & Cons

Assembly is child's play and no instructions are required. The perceived quality is excellent and the use is in line with what I expect from a brake disc.

Does what you can expect from a brake disc

Pros & Cons

Perfect, Shimano quality and super easy to install. The choice of fixing ring is a plus, depending on the tools you have. A reference

Easy to assemble

quality brake facilitation assembly

These brakes are ultra strong and powerful! They don't wear out quickly. Last indefinitely if you take good care of them of course. Moreover, they allow you to safely engage fast descents because they contain good cooling! Highly recommended for everyone!

Good disc with long life

Pros & Cons

Pros & Cons

Very neat and well made product

Pros & Cons

Works better than the previous version....

Pros & Cons

Made it to replace my Ultegra discs

Pros & Cons

Wow!!! When we assembled them we made bets!.... They seem to have more metal than the factory ones, but... when we weighed them WHAM.... 60 grams per disc less! Great! And how they brake! :)

Pros & Cons

Used as a replacement for the identical one, very good product

Pros & Cons

Bought these for the new wheelset. The old ones had a pair of Chinese budget discs on them and these brake noticeably better. Are also cheese straight in my case, so no hassle with run-up. Centerlock installation is also pretty easy, but you do need a casette tool, but you should have one anyway. Can't say anything about how they work after a lot of descending, but I'm sure they will.

Pros & Cons

Mounted on a Gravel, the discs are efficient. However, take into account the thickness of the star at the rear of the disc, which can rub on certain brake pad tongues.

Pros & Cons

better braking performance compared to the cheaper Chinese version that were on my Cube ebike.

Pros & Cons

Purchased for 2nd wheelset, easy to fit, good quality. Fit 2nd wheelset with no issues

Pros & Cons

I have been using these rotors for a month on bdc with organic pads. Fully satisfied with both quietness and especially braking feel.

Pros & Cons

Replaced old shimano rt800 s rotor, improved aesthetics and cooling system. Broadly satisfied, very good price here on Mantel.

Pros & Cons

Old Ultegra brake discs were only 1.4 mm thick. The new ones are 2.8 mm. This is also noticeable in the brake levers, which react quickly again (less deep pressure).

Pros & Cons

Super good , Shimano worthy

Pros & Cons

Easy to install, check jaw position and you're done.

Pros & Cons

I was totally satisfied with the precise description and the price of my item.

Pros & Cons

Normal great shimano product, these are better than road specific rotors and can be used on the road, solid, reliable, great confidence in dry and wet conditions.

The product I bought corresponds completely to the characteristics of the original parts.

Pros & Cons

I am very satisfied with the Shimano products

Disc mounted on a Gravel bike. Very satisfied with the braking

Pros & Cons

Shimano compliant, no worries.

Lighter than this they don't get, saving grams = winning!

Pros & Cons

Ideal for braking an electric mountain bike, with XT shifters, calipers and pads.

Pros & Cons

This version of Shimano Sheiben is more robust, and the same quality of the brand. I've heard of people who say that disc brakes are a disaster, but really important to tighten with a torque meter and calibrate properly.

Pros & Cons

The supplied lockring did not fit. mine had inside threads. The supplied lockring had outer thread. So I used the old one again.

Pros & Cons

Discs are perfect for enduro/dh use...always maintain high performance even during heavy use. Excellent shimano product.

Pros & Cons

Great belt pulley. Looks very nice and performs extremely well. Mounting the disc was a breeze thanks to the centerlock system. I highly recommend this disc!

Super discs, I also have XTR but these brake the same and the weight is also the same. I mounted these on my race bike.

Pros & Cons

on a racing bike, low to the ground

Vd basic Shimano disc to Xt. Highly recommended

Perfect with Shimano XT 4-piston calipers. Easy to fit. Powerful yet manageable braking. No noise, even in wet conditions. Very happy to have found it at Mantel at a reasonable price, in these times of shortage.
