The Shimano Disc Brake Assembled Set J-Kit Direct with the left-side ST-R7020 shift/brake lever and BR-R7070 front hydraulic disc brake caliper offers a premium braking solution for road and gravel riders who demand exceptional control and reliability. Specifically designed for 140mm rotor compatibility, this kit ensures superior braking modulation and consistent stopping power, tailored to the nuanced demands of technical riding and variable conditions.

At the core of this system, the BR-R7070 caliper utilizes resin brake pads enhanced with cooling fins to optimize heat dissipation, effectively reducing brake fade during intense or prolonged braking. This heat management system preserves braking performance on long descents or during rigorous rides, while also prolonging pad lifespan, making it suitable for endurance and competitive cyclists.

The ST-R7020 left lever is engineered to combine Shimano’s precise mechanical shifting with hydraulic brake actuation, allowing seamless integration of front derailleur control and braking within an ergonomic, comfortable interface. Its responsive lever design reduces hand fatigue and ensures intuitive operation, empowering riders with swift gear changes and confident braking response.

Complete with a comprehensive cable and hose package, this assembled set includes an 1800mm shift inner cable engineered for smooth and accurate front shifting, a 1000mm SM-BH90 hydraulic hose designed for optimal fluid flow, and a 600mm OT-SP41 outer housing that facilitates clean, efficient cable routing. These components simplify installation while maintaining system integrity and performance.

Finished in a sleek black color, this OEM-packaged set combines Shimano’s hallmark durability, innovative design, and refined aesthetics. The Disc Brake Assembled Set J-Kit Direct delivers a sophisticated hydraulic braking and shifting experience, enabling cyclists to tackle diverse terrain and riding conditions with enhanced precision, control, and confidence.
