SHIMANO SW-S705R ALFINE Di2 shifter right

The SHIMANO SW-S705 shifter is the interface between the rider and their electronic DI2 ALFINE or NEXUS hub. Whether 8-speed or 11-speed doesn't matter. The shifter can be programmed accordingly via SHIMANO's E-Tube Project platform. It is integrated into the system via the EW-SD50 cable.

Its design ensures a tidy cockpit. The high-quality workmanship guarantees a long service life. The switch can be positioned anywhere on the handlebars thanks to the clamp attachment.

Technologies

SEIS
A technologically innovative, computerised shifting system based on the DI2 concept called SEIS (SHIMANO ELECTRONIC INTELLIGENT SYSTEM). The innovative shifting technology of the SEIS is still based on the SHIMANO INDEX SYSTEM (SIS), whose outstanding shifting performance has proven itself over many years. The main difference between the systems is that the shifting process is no longer mechanical, but electronic. This electronic shifting system has been extensively tested in recent years by several professional cyclists in all conceivable conditions, e.g. rain, mud, extreme cold, cobblestones and a combination of these factors.
Shifting is done by simply pressing a button. No effort is required to shift gears, which has clear advantages as the rider always has a firm grip on the handlebars and can concentrate on riding without being distracted by shifting gears. The shifting system enables precise and effortless shifting in all situations, even with cold hands or when the rider is completely exhausted. The shifting performance can also no longer be affected by dirty or stretched cables, as the shift signal is transmitted electronically. The operating buttons work in a similar way to mechanical DUAL CONTROL levers, making it easy to get used to the SEIS.

E-TUBE PROJECT
is an application that allows you to update your bike's firmware and change the DI2 settings when the bike is connected to a PC, tablet computer or smartphone.

• Individual setting - Customise functions and operations as you wish. Find the settings that suit your personal riding style.
• Update firmware - The programme automatically checks whether new firmware is available every time you restart. This keeps you up to date at all times.
• Fault diagnosis - In the event of anomalies, you can immediately carry out a diagnosis with the app. The unit in question is determined so that you can take care of a repair quickly and easily.
