Shimano XTR BR-M9100 XC Disc Brake J-Kit

The Shimano XTR BR-M9100 XC disc brake keeps you in control

The Shimano XTR XC BR-M9100 disc brake comes with the all-new BL-M9100 brake lever. Its angled clamp is located more centrally than its predecessor, so that the reservoir is supported at the outer end by the handlebars. The result is increased rigidity, a more direct braking sensation and greater overall control. Weight-saving carbon and magnesium were used for Cross Country applications. Another novelty is the I-Spec EV mounting option for integrating a shifter with even more adjustment options. The one-piece aluminium brake calliper with 2 ceramic pistons stands for reliable Ice-Tech brake power, stability and low weight and can be bleed very easily using One Way Bleeding.

Technology:

I-Spec EV
I-Spec EV describes a variant of the connection between brake lever and shift lever on Shimano MTB derailleurs. This type of mounting allows the shifter to be adjusted both horizontally and vertically in relation to the brake lever, and ensures a tidy cockpit by reducing the number of clamps required. Compared to I-Spec and I-Spec II, I-Spec EV offers a much wider adjustment range. 14 mm adjustment range the longitudinal direction and up to 60° rotation allow an optimal ergonomic adjustment to your riding style, your sitting position and your anatomy.

One-Way Bleeding
One Way Bleeding is a technique used on Shimano calipers that facilitates brake bleeding. The hose routing has been optimised so that no air bubbles remain in the brake calliper. In combination with the funnel, the brake can be bled cleanly and easily.

J-Kit
J-Kit is a simple line connection system for hydraulic brakes from Shimano, so that you can install your brakes quickly and easily. The brake hose does not come connected to the brake to facilitate routing of the hose in the frame. The brake hose is already filled with oil in the J-Kit and sealed with a thin membrane. There is a small pin in the J-Kit brake lever that pierces this diaphragm during assembly to allow oil to flow.
