Shimano DURA ACE Di2 R9250/R9270 2x12 Speed ​​Upgrade Kit

SHIMANO's Di2 Dura Ace shifting systems use wireless technology wherever it is deemed appropriate for everyday riding and top sports performance. The separation of the physical connection between the shift levers and the rear derailleur ensures a tidy cockpit and also simplifies the installation process. At the same time, the connection of the shifting components to the internal battery ensures absolute reliability thanks to the stable power supply.

SEIS SHIMANO ELECTRONIC SMART SYSTEM

The innovative shifting technology of SEIS is still based on the SHIMANO INDEX SYSTEM (SIS), which has proven its superior shifting properties over the years. The biggest difference is that in this case the shifting action is provided electronically instead of mechanically. This electronic shifting system has been extensively tested by many professional riders over the last two years in all possible conditions, such as rain, mud, low temperatures, cobblestone roads and a combination of all of these at the same time. Shifting is done by simply pressing the button. No force is required to change gears, which provides significant advantages because it is now easier to keep a firm grip on the handlebars at all times and focus on riding instead of shifting gears. The shifting system enables accurate and effortless shifting in difficult situations, such as when your hands are cold or you are completely exhausted. Furthermore, since the shift signal is transmitted electronically, shifting performance will never be affected by dirty or stretched cables. The actuation buttons work similarly to mechanical Dual Control Levers, so you don’t have to reprogram your mind for a new system.

E-Tube
The E-Tube platform offers optimum flexibility on your bike. E-TUBE transmits interactive signals and power supply to each component via “Plug & Play” connection. E-TUBE is rust-proof, stretch-proof, frost-proof and requires advanced low maintenance. And SM-PCE1 connects the components to the computer to update the firmware. The digital device updates the firmware to improve the function and maintains the latest version.
Shimano Shadow RD
The Mechanism Rear Derailleur SHIMANO SHADOW RD is designed for more aggressive riding. Its super low profile design provides many benefits. Due to its low profile and single stress structure, the derailleur does not hit the chain stay in harsh riding conditions. The result is smooth and quiet performance.
