Ultegra Di2 shift / brake lever for mechanical rim brakes
The sleek new wireless cockpit impresses with its simple operation, tidy aesthetics, improved ergonomics and increased ease of maintenance. All of this is made possible by the new wireless system that we have developed for even faster switching - without compromising on precision and reliability. Road cycling has never felt so good. The revised ULTEGRA ST-R8150 levers convince with new ergonomics and even more precise brake modulation thanks to the proven SERVO WAVE technology from SHIMANO. Wireless electronic switching provides even more control.
Highlights
- Fast and intuitive switching
- Clearly defined click feeling with ergonomic gear lever
- Better control and confidence in racing conditions
- The croissant shape and surface structure ensure optimum grip and braking force transmission

Technologies used
In this chapter we explain the technologies that the manufacturer uses for this product.
SLR-EV
SLR-EV is a SLR with a symmetrical dual pivot side-pull brake. The short arm brake design uses two bearings and a roller to achieve greater efficiency in the joint area and provide superior dosage and power when braking. Together with the BC-9000 brake cable, the latest brake calipers offer 36% more braking power than the previous SHIMANO brake model. And we offer versions with a symmetrical 2-axis brake body as well as versions for fork mounting and chain stay mounting.
Reach Adjust
The brake lever is equipped with a reach adjustment. This means that the handle adapts to the size of the driver's hand or to his driving style or personal preferences.
DCL - Dual Lever Control
DCL stands for Dual Lever Control (DUAL Control Lever). It has braking and switching functions and is easy to operate. The improved ergonomics are probably even more important for the high standard than additional translations. The technology of the new gear levers brings the stability of Shimano's MTB technology and works so precisely and smoothly that it is possible to shift front and rear with just one finger. This is really a highlight of Shimano Total Integration. To understand that, you just have to experience it for yourself.
The dual control shift / brake levers from DURA-ACE, ULTEGRA and 105 have been optimized and now have, for example, a weight-reduced joint on the inside of the shift mechanism and integration of the shift cable for easier steering. The extremely compact and high-precision manufactured individual parts result in an unmatched switching speed when combined.
E-Tube Project - settings that can be adjusted via the app
The E-Tube Project application for mobile devices developed by Shimano has functions for customizing the bike, updating the firmware and for maintenance using a wireless connection to the bike. More detailed maintenance of the bike is possible by connecting the bike to the E-Tube Project for Windows V4 application using a cable.
