SHIMANO ULTEGRA Di2 ST-R8070 Brake/Shift Lever Combination Rear Wheel with BR-R8070 Disc Brake (J-KIT DIRECT)

Precise shifting, combined with a strong, well-modulated braking power, characterise the ULTEGRA BR-R8070 shift/brake lever combination with the BR-R8070 hydraulic flat mount brake calliper by SHIMANO for road and cross bikes. Even in adverse weather conditions, you will enjoy the feeling of safety and riding pleasure on your road bike.

The SHIMANO ULTEGRA ST-R8070 STI brake/shift lever combination has everything you need to set your bike up perfectly in the race against time. It is not only the slimmer styled handle horns that lead to improved ergonomics and thus to better intuitive control. Electronic shifting via the Dual Control (STI) levers gives the ultimate feeling of individual precision. Even with thick gloves, the clear separation between the shift buttons is noticeable thanks to better click feedback.

With Synchro-Shift, the rear derailleur and front derailleur can be operated with one shift knob for optimal positioning of the gears. Under the top cover of the brake lever combination, there are also programmable buttons for controlling gear changes, third-party devices or compatible additional components such as bike computers. Multi-Shift can be switched on or off individually. All Di2 settings, from shifting speed to Synchro-Shift and Multi-Shift options, can be easily be adjusted via the SHIMANO E-tube app.

Enjoy optimum control, as the ULTEGRA BR-R8070 hydraulic flat mount calliper offers a firm grip for more stable braking performance and integrates aerodynamically with your bike's frame and fork.
