SHIMANO SYNCHRONIZED SHIFT

With the customization of the E-TUBE PROJECT app, both front and rear derailleurs are automatically selected for the most optimal gear combination.

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.

What is SHIMANO SYNCHRONIZED SHIFT?

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.

Exclusive functions

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.

Semi-SYNCHRONIZED SHIFT

•This function automatically shifts the rear derailleur when the front derailleur is shifted, allowing the derailleurs to work together efficiently. Equipped: DURA-ACE R9150 series, ULTEGRA R8050 series.

SYNCHRONIZED SHIFT is a function that automatically selects the most efficient gear on the front derailleur in synchronization with rear derailleur gear shifting.

SEMI-SYNCHRONIZED SHIFT is a function that automatically selects the rear derailleur gear position to obtain the optimal gear step transition when the front derailleur is shifted.

This gives you more control to match the gear combination to your personal riding style.
