The Shimano FD-R9150 [paid link] Di2 front derailleur is a highly customizable electronic shifting component that offers precise, fast, and automatic gear changes. Unlike mechanical derailleurs, the FD-R9150 [paid link] can be fine-tuned through Shimano’s E-TUBE PROJECT software, allowing riders to optimize shift speed, trim settings, and multi-shift functions for their riding style.

This guide covers how to connect the FD-R9150 [paid link] to E-TUBE PROJECT, customize its settings, and troubleshoot common issues.

What is Shimano E-TUBE PROJECT Software?

E-TUBE PROJECT is Shimano’s Di2 system management software that allows cyclists to:

  • Update firmware for derailleurs, shifters, and junction boxes.
  • Adjust shift speeds and derailleur positioning.
  • Enable multi-shift mode to shift multiple gears with one press.
  • Customize Synchro-Shift settings, so the front derailleur shifts automatically based on rear cog selection.

This level [paid link] of customization ensures smoother, more intuitive shifting based on individual riding preferences.

Connecting Shimano FD-R9150 to E-TUBE PROJECT

Before adjusting settings, the FD-R9150 must be connected to the software.

  1. Install Shimano E-TUBE PROJECT software on a PC, tablet, or smartphone.
  2. Turn on the Di2 system and make sure the battery is charged.
  3. Connect your bike to the device using either:
    • A wireless connection (for Bluetooth-enabled Di2 models).
    • A wired connection using Shimano’s SM-PCE02 interface device.
  4. Launch E-TUBE PROJECT and wait for the software to detect the FD-R9150 front derailleur.

Once connected, the software will check for firmware updates. If an update is available, install it before making any adjustments.

Customizing FD-R9150 Shift Settings

The E-TUBE PROJECT software allows several key adjustments to improve shifting precision.

Adjusting Shift Speed

By default, the FD-R9150 shifts at a standard speed, but this can be increased or slowed down based on rider preference.

  • Faster shifting improves responsiveness for racing and sprinting.
  • Slower shifting ensures smoother gear changes for touring or endurance rides.

To adjust shift speed:

  1. Open E-TUBE PROJECT and select the FD-R9150 derailleur.
  2. Navigate to “Shift Speed Settings.”
  3. Choose between Fast, Normal, or Slow settings.
  4. Save and apply the changes.

Enabling Multi-Shift Mode

Multi-Shift Mode allows multiple shifts with a single button press, making it easier to change gears quickly during climbs or sprints.

To enable multi-shift:

  1. Open E-TUBE PROJECT and select the shifter settings.
  2. Activate Multi-Shift Mode under the front derailleur settings.
  3. Adjust the number of gears shifted per button press (typically 2–5 shifts).
  4. Save and test the new settings on the road.

Customizing Synchro-Shift Mode

Synchro-Shift Mode automatically shifts the FD-R9150 front derailleur based on rear cog position, ensuring the rider is always in an optimal gear ratio.

There are two modes:

  • Full Synchro-Shift: The front derailleur shifts automatically based on cassette gear selection.
  • Semi Synchro-Shift: The rear derailleur compensates automatically when the front derailleur shifts, ensuring consistent cadence.

To enable Synchro-Shift:

  1. Open E-TUBE PROJECT and navigate to “Synchro-Shift Settings.”
  2. Select Full Synchro-Shift or Semi Synchro-Shift based on preference.
  3. Save changes and test shift transitions during a ride.

Troubleshooting E-TUBE PROJECT Connectivity Issues

If the FD-R9150 is not detected by the software:

  • Ensure the Di2 battery is fully charged. A low battery can disrupt connections.
  • Check E-TUBE cable connections. Loose or damaged cables may prevent detection.
  • Use a different device if the connection is unstable. A wired connection via SM-PCE02 is more reliable than Bluetooth.
  • Update the software and firmware to the latest version.
