As with the current STI levers of the Dura Ace and Ultegra series, Shimano has again collaborated with professional riders in the development of the electronic 2x12-speed control units of the 105 series. Not only that also a Wireless system has found its way to provide a tidy and wonderfully minimalist cockpit, also at the ergonomics was extensively tweaked. Characteristic of the revised aesthetics and aerodynamics are above all the raised lever hoods, which prevent fatigue regardless of the hand position and ensure first-class comfort.
Featuring an reach adjustment mechanism allows adaptation to different hand sizes or riding styles and thus promises more control in racing, the button functions that can be individually assigned via E-Tube app benefit an essential task of the control units: the shifting performance. A self-developed circuit ensures reliable and fast signal transmission, which not only enables more precise and direct shifting processes in manual mode, but also more intuitive ones. Athletes who want to devote themselves fully to racing can also leave the gear changes completely or at least partially to the Synchronized Shifting technology.
The switch to electronic Di2 shifting naturally also offers decisive advantages in terms of ease of maintenance. With a battery life of at least 3 years, no rider needs to worry about powering the wireless shift/brake levers either. Speaking of brakes, with an extended control range, also the smooth Servowave brake levers experienced a significant upgrade in terms of dosage and deceleration performance.

- SERIES: SHIMANO 105 Di2 R8100 Series
