Fantastic performance on and off road, a must for replacement road rotors
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.

This product is just phenominal!
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!

Cool & Sexy!
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!

Good stuff
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.

shimano quality at its best.
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.

Super fine brake disc
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.

I would definitely buy them back
Braking power is excellent even on long descents , having the ability to cool down well (I am 92 kg) , while holding an aggressive ride.

Stealthy looks
Great easy assembly. Just make sure when tightening the centerlock that you keep the tool straight otherwise you will scrape the disc brake.

Excellent braking performance with calipers from the same group
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.

Fine, lightweight brake discs
Lighter than this they don't get, saving grams = winning!

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

good product
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

Great quality
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.

The heat sink that looks great on your wheel
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! :)

Great replacement for the old Ultegra brake discs
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

I recommend
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.
