Shimano Deore XT M8100 - The world is your canvas
The legendary MTB group set to set the standard for mountain bikers around the world, even in the latest generation. For nearly three decades, the Deore XT has been synonymous with trailer-proven durability, reliability and performance. As mountain biking gets faster and the terrain more technically challenging, the job of the M8100 components is to give the rider the confidence he needs to get the most out of the bike.

Typically Shimano, the Deore XT also features the innovations of high-end XTR parts. Consequently, Micro Spline and Hyperglide+ are on board with the new 12-speed groupset.

The Shimano Deore XT M8100 Enduro brake set consists of the ergonomic BL-M8100 brake lever and the powerful BR-M8120 4-piston brake caliper. The proven One Way Bleeding and Easy Hose Joint System, which facilitates brake line replacement, ensure easy and trouble-free maintenance.

J-Kit (Easy Hose Joint System)
On brake systems with a J-Kit brake line connection, the brake lever has an integrated pinch seal (olive), which greatly simplifies overall brake line installation and removal.

Shimano Deore XT BL-M8100 Brake Lever
The Shimano Deore XT BL-M8100's brake lever clamp is angled, so the outer end of the reservoir cleverly rests directly on the handlebars. The two contact points created in this way provide significantly increased stiffness, ultimately resulting in more direct feedback and therefore greater stopping power.

Shimano's SERVOWAVE technology also serves to improve braking performance, ensuring particularly good dosage. Because the brake lever occupies a lot of stopping distance right at the beginning of its movement, the brake pads contact the brake rotor more quickly, leaving more lever travel to modulate braking force. Consequently, SERVO WAVE braking systems are characterized by faster reaction, higher power and shorter idle travel.

The BL-M8100 is 10% stiffer than its predecessor, even at high temperatures. The width of the brake lever is directly adjustable without additional tools. Thanks to the I-Spec EV construction, the Deore XT SL-M8100-I controls can be mounted directly to the brake lever.


Shimano Deore XT BR-M8120 Disc Brake Caliper
The Shimano Deore XT BR-M8120 Postmount brake caliper, with its 4-piston construction, is ideal for trail and enduro use. By accelerating the reset of the pistons, the modulation behavior has been further improved compared to its predecessor, resulting in better brake control. The N03A resin or N04C metal brake pads with Ice-Tech cooling fins in combination with the powerful 4-piston brake caliper guarantee extremely good deceleration. In addition, the 4-piston design reduces brake disc vibration noise and increases braking force by 10% compared to the BR-M8020 caliper.
