Pros & Cons

Pros & Cons

  • The heat dissipation of this brake disc is very good by Shimano's Ice-Technology Freeza.
  • Due to the harder material, this brake disc can also be used with Semi-Metallic and metallic brake pads.
  • This brake disc is made of light materials and therefore has a low weight.
  • You can choose different sizes of locking rings with this brake disc, so you don't have to buy extra lock rings with a 15 mm through-axle.
  • This brake disc is slightly heavier than the XTR MT-900 brake disc.

Description

Description

The Shimano XT RT-MT800 brake disc is a low weight disc with optimal heat dissipation and is designed to maximize your braking performance!

Heat dissipation with Ice-Tehnology Freeza
This brake disc is equipped with Shimano's Ice-Technology Freeza heat management. This means that the brake surface of the disc consists of three layers: 2 layers of stainless steel and 1 layer of aluminium. Ensuring the disc has excellent heat dissipation, which means that you'll be able to maintain good braking power for longer periods of time on long downhill runs when braking often. Both fading and heating of the oil, will be less likely to occur. This will allow you to go downhill with more confidence and braking power!

Hard material, optimally milled
The components of this disc are milled out of hard materials. This allows you to ride with harder brake pads than just the traditional Shimano Resin brake pads. Harder pads do not heat up as fast in long descents and have a higher durability.

Low weight
Shimano has done its best to keep this brake disc's weight as low as possible, without compromising its functionality. With this disc, you won't have to waste power lugging extra grams up hill while experiencing enough braking power going downhill.

Lockring variants
This brake disc is available in all sizes with a lock ring that has internal toothing. It is compatible with Quick-release axles, and with 10 mm and 12 mm through-axles.
The 140 mm and 160 mm brake discs are also offered with a lockring with external teeth. This lockring can be tightened with a bottom-bracket wrench and is mainly used for 15 mm axles.

Type of bike
This XT RT-MT800 has been developed for the XT mountain bike series. However, this brake disc can also be used on trekking bikes, road bikes, city bikes and e-bikes.

Technology

Type of bike
These XT RT-MT800 discs are designed for the XT MTB series. They also work well on touring bikes, road bikes, and city and e-bikes.

Heat dissipation through Ice-Tech Freeza technology
These rotars feature Shimano's Ice-Tech Freeza heat management technology. The brake surface consists of 3 layers: 2 of stainless steel and 1 of aluminium. As a result the heat dissipation is very good, so you'll still have good braking power on long descents which require being on the brakes for a while. Brake fade as well as brake oil overheating is also less likely, so you can have more confidence in your braking power.

Stealthy looks

- Bernd 2 February 2021

Geweldig makkelijk te monteren. Zorg er alleen voor dat je bij het aandraaien van de centerlock het gereedschap recht houdt anders schamp je de schijfrem.
