What our customers are saying about Shimano XT RT-MT800 CL Disc brake disc

This high-quality brake disc rotor provides powerful, solid braking with excellent heat dissipation, preventing overheating even on long descents. Praised for its fantastic quality-to-price ratio, this center lock rotor is a top performer. It features a high-tech, aesthetically beautiful design that looks massive and powerful on any MTB. Available in 180mm (5-spoke) and 160mm (4-spoke) sizes, it works great with both Shimano and Alligator brake pads, making it a perfect, lightweight upgrade for reliable performance

Good product...but

2025/11/27

Lionel

The disc itself is perfect; it offers braking that is both powerful, efficient, and consistent. However, I struggled to find the correct caliper adapter because I have a 4-piston XT BR-M8120 caliper from the same brand, and the model that corresponds to the XT BR-M8100, according to the chart provided by the brand, doesn't allow the caliper to fit. I had to take my mountain bike in pieces to the dealer to find one from another brand so I could mount the correct caliper for the disc. Thanks, Shimano.

The best brake disc you can use, good performance and an unbeatable look. Shimano never disappoints, and at the price they're offering, it's worth it.

Perfect package, but I received the notification that my package had left the warehouse on Thursday at 7 a.m. and it arrived at 10 a.m. I received the notification that it had arrived only at 12:34 a.m. Isn't that normal?

180 and 160 rotors

2025/06/04

Zoran

I purchased 180 for the front and 160 for the rear. They look amazing, braking too!! There is a slight difference in appearance, the 180 has 5 black spokes and the 160 has 4 black spokes. They look massive and powerful, I would buy it again.

Top quality

Just delivered and already installed. Bought to replace my old disc which was 1.2mm thick and at the end of its life. Works great with Alligator pads.

I purchased the 180 mm version to put them on the rear of my MTB, they are excellent, solid braking and aesthetically very beautiful. I did long braking at high speed and they didn't cause any overheating problems.

Shimano XT RT-MT800 CL Disc Brake Disc

Roberto

Does this disc have the outer center lock ring?

Answer of David

Yes, it has the closing ring.

Answer of Adolfo

Yes, it is a center lock with an external mounting ring.

Answer of Agostino

I bought 2 of them, and they had an external central locking system.

Fulcrum Red carbon 3

Siddi

Hi, they are compatible with Fulcrum Red carbon 29 center look system. Thanks

Answer of David

If it is centerlock yes.

Answer of Adolfo

If the locking system is both central and external, they are compatible. If they are internal central locking, they are not. The ones that worked for me were external Centerlock (large threaded ring).

external or internal dentition

2025/10/04

SANDRO

Does the RT-MT800 160 have external or internal teeth? Does the RT-MT800 180 have external or internal teeth? Do they have magnets? It doesn´t say... Thanks

Answer of David

All centerlocks are the same. The difference is in the locking mechanism. The brake discs don´t have magnets.

Answer of Adolfo

The last time I ordered them, they were sent to me in 203 mm and the following model: External serration = the teeth are on the outside of the hub, and an external lockring is used, which is tightened with a cassette wrench (such as the Shimano TL-LR15 or TL-FW30). Thanks.

External or internal serration lockring

2024/11/25

jure

On picture it is external serration (tooth for tightening on outer side of lockring, no serration on inner side). Can you confirm that it is external serration

Answer of Alessandro

Good morning, the only difference between the front and rear are the two clamping rings, the front is external and requires an external key, the rear is internal and requires a Shimano internal key but both are super quick to remove and assemble.

Will they fit my giant ebike?

2024/09/25

Toni

I have Shimano disc brakes with center lock...and they both have the crown on the outside...could you tell me which models I should buy for the e-bike I have...I need the one on the back to have a magnet. Thanks

Answer of Alessandro

If the magnet is not snap-on and is made of plastic, you need to buy the disk with a built-in magnet, it costs a little more. Bye

denis

bruno

Hello, is the disc in question compatible with racing bikes? And is the locking ring external or internal?

Answer of Antonio

It is road compatible. I don´t have much control over the ring, a friend gave it to me

Internal or external thread?

2023/12/17

Roman

Hello, is it with external thread?

Answer of Alessandro

Hi, you don´t have to look at the disc because of the thread, but you have to look at the Center Lock i.e. the locking ring if it is internal or external. The disc has no thread

Answer of Anita

It´s center lock. It doesn´t have 6 screws

Answer of Cesar Manuel

Hello, yes, this model has an exterior center lock.

front or rear wheel

2023/08/02

Carlos

Hello, I have seen on some page that they talk about external or internal closure, is this disc valid for the front and rear wheel? Is it installed with the bottom bracket tool? Do I have to keep something in mind? I have seen that on your page there are 2 and with little difference in price. Thank you very much for the information

Answer of Ricardo

Hello, I have them mounted on both wheels. For the closure of the rear wheel I had to put the original one from my e Bike because it has a magnet and the one that comes with the wheel is from Shimano, this magnet does not work well for the turbo levo. The front closure is with a bottom bracket key, the rear with a cassette key. I hope I have helped you. Regards.

Closing

Víctor

Internal toothed closure?

Answer of Pavel

Yes, this brake disc has a "serrated" rotor mounting system of the "Center Lock" standard. Shimano Center Lock is a development by Shimano that allows easy and quick installation of the rotor on the wheel hub.
