Features:

- Use: Road

- Model: Shimano Ultegra Di2 R8170

- Speed: 2x12V

- Weight: 391 g (pair)

- Brake lever: Recommended brake caliper BR-R8170

Technologies:

- SERVO WAVE: when pulling the SERVOWAVE brake lever, the initial stroke of the pads is rapid, so a slight movement of the lever is sufficient to bring the pads into contact with the brake disc. The power multiplication factor then increases rapidly at the "pad/rim" contact point, so that lever travel can be used to apply more braking power with greater control.

- Reach Adjust: the brake lever has a flow control mechanism. You can adjust the distance between the handlebars and levers to fit any size, respecting the rider's preferences.

-DCL: DCL stands for DUAL CONTROL LEVER. It incorporates brake and shift functions into the system and allows easy operation.

The Ultegra R8170 2-piston Shimano hydraulic brake caliper offers improved modulation, a quieter braking system and an easier bleeding process than ever before. The disc brake caliper brings a new level of control to the world of road cycling, with better modulation and a faster initial braking point. Despite its smaller construction, the system is quieter than ever and easier to maintain.

Technologies:

- ONE WAY BLEEDING has been developed for quick and easy prevention of air in the hydraulic system. They streamlined the oil path in the system to avoid air bubbles in the system. The one-way oil path, plus a funnel tool for mineral oil, provides an easy and clean purge system.

- ICE TECNHNOLOGIES: Overheating, which can occur in the disc and pad when braking on long descents, has a negative impact on braking performance. Shimano has adopted the ICE TECHNOLOGIES brake disc to create cooling technology that guarantees reliable performance. The coated disc blade, with a three-layer sandwich structure of stainless steel, aluminum and stainless steel, offers better irradiation performance.

The hydraulic rear disc brakes Shimano Ultegra Di2 2x12V have been redesigned and feature completely new ergonomics, even more precise brake modulation and wireless electronic shifting.
