Product Description

Please note: all of our bike models come with an EU standard brake setup. This will need to be reversed to comply with UK cycling standards.

The new XT components set a completely new quality standard in the MTB sector. Powerful for efficient power transmission and fast responding braking force. Dynamic with "Rider Tuned" 11-speed transmission combinations for outstanding performance. Robust and reliable even on the roughest trails.
The new hydraulic 4-piston disc brakes fit seamlessly into the Deore XT component lineup. They have been designed to allow aggressive driving even in the most demanding terrain while providing safety reserves. The new stoppers use Shimano's Iice-Tech heat management system to design the calipers, compatible discs and pads.

Servo Wave
The Servo-Wave brake lever takes up a lot of braking distance at the beginning of its movement so that the pads can be guided to the brake disc with a short lever travel. After the brake pad has been applied, the power transmission factor increases rapidly. This means that the greater part of the lever travel is still available to increase the braking force and to control it more precisely.

I-Spec II
The XT levers are compatible with the I-Spec II system, which allows the shift and brake levers to be mounted on the handlebars with just one clamp, giving more freedom in cockpit design, saving weight and improving ergonomics with a wide range of adjustment options. Easy to assemble with narrow brake lever clamp. More space on the handlebars and a tidy look.

One-Way Venting
One-Way Ventilation is designed to quickly and easily prevent air from entering the hydraulic system. Shimano has optimized the routing of the brake fluid throughout the system to prevent air bubbles from trapping in the system. The brake fluid's one-way path, together with the funnel for filling the mineral oil, allows clean, trouble-free bleeding.


  • even, predictable and powerful
  • simple and clean ventilation with one-way bleeding
  • powerful, controlled braking for all MTB riding styles

Watch out, the brakes!
Pass auf, die bremst!
Translated from German To the original

Simply great I was looking for a replacement for my MPH squeak brake. The Shimano XT brake is quick to install (there are videos on YouTube for absolute beginners). also fits on a bike that is no longer new and does what it has to do after braking and that makes it perfect. On longer Dowhills, the brakes get a little more aggressive. You have to feel that. Otherwise, if it gets really steep, the thing will throw you over the handlebars. It's a lot of fun and also enhances your bike.

Einfach Super Habe einen Ersatz für meine MPH Quitsche-Bremse gesucht. Die XT Bremse von Shimano ist schnell montiert (Für absolute Anfänger gibt es Videos auf Youtube). passt auch auf ein nicht mehr neues Bike und macht, nach dem einbremsen, wass sie muss und das macht sie perfekt. Auf längeren Dowhills wird die Bremse sogar stetig etwas agressiver. Das muss man spühren. Wenn es wirklich steil wird, schmeisst dich das Ding sonst über den Lenker. Macht viel Spass und wertet auch dein Bike wieder auf.

Always happy
Immer wieder gern

I already had the brake on my old Specialized (pre-assembled) and was very satisfied. After years I have brought it back to me only for my giant. The brake came as a kit. Long story short ... I'm a layperson, but I'm not afraid of much. Cables laid through the frame, assembled, vented and ready. A good brake with decent performance (I have 100kg)

Ich hatte die Bremse schon an meinem alten Specialized (vormontiert) und war sehr zufrieden. Nach Jahren habe ich sie mir nun wieder geholt, nur für mein Giant. Die Bremse kam als Bausatz. Lange Rede, kurzer Sinn.... Ich bin Laie, aber scheue nicht viel. Kabel durch den Rahmen verlegt, zusammen gebaut, entlüftet und fertig. Eine gute Bremse mit ordentlich Leistung (ich habe 100kg)

Good brake, poor support
Bra broms, dålig support
Translated from the Swedish To the original

You had to assemble hydraulic hose for brake handle yourself. There was no instruction on how. Called support who promised to check and return. They didn't. Got to figure out how to cut hose and assembled. The brake itself works super shaved.

Man fick själv montera ihop hydraulslang till bromshandtag. Fanns ingen instruktion om hur. Ringde support som lovade kolla och återkomms. Det gjorde dom inte. Fick själv lista ut hur man kapade slang och monterade. Bromsen i sig funkar superberbt.
