Shimano Deore XT BR-M8100 Hydraulic Disc Brake Caliper Kit Front BlackThe Shimano Deore XT BR-M8100 Hydraulic Disc Brake Caliper Kit uses a pre bled system for the front or rear to give extreme control and adjustability to your stopping power for maximum efficiency. The greater flexibility and action-optimized cockpit layout allows the brake engagement with a shorter free stroke. The super lightweight 2 piston caliper pre-bled design makes setting it up quicker than ever, and the toolless adjustment make these appealing. J-Kit Technology: For some frames with internal routing, the J-Kit version may be easier to install, since everything is pre-bled. Disconnected lever comes pre-bled with connecting bolt/built in olive pre-installed. Brake caliper is pre-bled with brake hose connected/capped. Available in Front 1000mm and Rear 1800mm.192790445915
