Shimano Deore BL-M4100 + BR-MT420 Enduro / Trail Hydraulic Disc Brake - J-Kit - Set RW

Shimano Deore M6100, M5100 & M4100

After the mountain bike flagship XTR has already set benchmarks and Deore XT and SLX have followed suit, the Deore M6100 now rounds off Shimano's 12-speed lineup. It is complemented by the components of the M5100 and M4100 series which will equip 11- and 10-speed drivetrains at the same high level.

Regarding the price, the current Shimano Deore groups are positioned in the entry-level range, but are not prepared to compromise in terms of performance, quality and reliability. Almost everything that the high end groups XTR, XT and SLX have to offer in terms of technology, innovation, performance and range of functions, you will find in the Deore components, too.

Shimano Deore M4100 brake set consisting of the BL-M4100 2-finger brake lever and the BR-MT420 4-piston caliper. The result of the combination is a solid brake performance in any condition. Trouble-free maintenance is provided by the proven One Way Bleeding concept and the Easy Hose Joint System which simplifies brake hose exchanges.

J-Kit (Easy Hose Joint System)

At brake systems with J-Kit hose joint the brake lever features an integrated olive what makes an easy brake hose installation and removal possible.

Shimano Deore BL-M4100 brake lever

The construction of the hydraulic Shimano Deore BL-M4100 brake lever is inspired by XTR, Deore XT and SLX series, so the clamp is not mounted parallel, but with an angle to the handlebar creating a second contact point which provides significantly increased stiffness. For individual customizability, the 2-finger brake lever is equipped with an integrated, tool-based reach adjustment option. Thanks to the I-Spec EV design the Deore SL-M4100-I shifting levers can be mounted directly to the brake lever.

Shimano BR-MT420 disc brake caliper

The hydraulic Shimano BR-MT420 disc brake caliper features a 4-piston construction but is nevertheless characterized by a slim design. The 4 resin pistons offer 20 % more braking power than the 2-piston version and guarantee reliable deceleration and control on Downhill tracks. Even the wear resistance could be improved by 150 % compared to the BR-MT400 caliper. Postmount compatible.
