Shifting has never been so precise
Refined with feedback from pros, the new wireless dual-control lever offers more control and unparalleled ergonomics, including a raised canopy tip and smoother, lighter leverage. The reach adjustment mechanism means the distance between the handlebars and the lever can be adjusted to suit any hand size and riding style. In addition, the braking area has been increased to allow more control when braking.

Technologies used
In this chapter we explain the technologies that the manufacturer uses in this product.
Reach Adjust
The brake lever is equipped with a reach adjustment. This allows the grip to adapt to the size of the driver's hand, his driving style or personal preferences.
DCL - Dual Lever Control
DCL stands for Dual Lever Control. It has braking and shifting functions and allows for easy operation. The improved ergonomics are probably even more important for the high standard than additional gearing. The technology of the new shift lever 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 this, you simply have to experience it yourself. The dual-control shift/brake levers on the DURA-ACE, ULTEGRA and 105 have been optimized and now feature a weight-reduced joint on the inside of the shifting mechanism, for example, and the shift cable has been integrated for easier steering. The extremely compact and high-precision manufactured individual parts result in an unrivaled switching speed.
E-Tube Project - Settings customizable via the app
The E-Tube Project mobile application developed by Shimano has functions for bike customization, firmware update and 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 application for Windows V4 using a cable.
