Benefits & Features
・ Intuitive shifting allows the rider to easily operate both derailleurs with a single shifter.
・ Automatic gear selection avoids sudden changes in gear ratio, providing efficient pedaling and shifting stress reduction.
・ The E-TUBE PROJECT app lets riders set their own personalized shifting preferences.
SHIMANO SYNCHRONIZED SHIFT’s advanced shifting technology allows you to program and execute multiple commands of your choice, with a single shifter. Not only do you choose when the front derailleur shifts, you can program simultaneous rear shifts to maintain cadence and momentum. However, if you’d like a left shifter, it can be used as well. It
would allow you to manually execute a front shift whenever you wanted, but most riders don’t find that necessary.
SYNCHRONIZED SHIFT automatically shifts the front derailleur when the rear derailleur is shifted, allowing the derailleurs to work together efficiently. It gives riders the simplicity of 1x11 drivetrain, with the gear range & gear steps of a 2x11
drivetrain by utilizing a single gear shifter (or two shifters if you prefer) that can control both the front and rear derailleurs through programmable gear mapping.
Two derailleurs, One Shifter
•Front derailleur reads the rear derailleur’s position and automatically executes front shifts.
•Improves efficiency by minimizing time spent on smaller chainwheels.
Programmable synchronized shifting map
•The rider chooses when front shifts occur and also chooses rear derailleur command.
Shift options
•Switch between manual and SYNCHRONIZED SHIFT modes.
