The Shimano SM-PCE02 is the essential interface tool for connecting your Di2 electronic shifting or STEPS eBike system to a PC. Used by mechanics and enthusiasts alike, it enables firmware updates, system diagnostics, customisation of shift behaviour, and recovery of non-responsive components — all via Shimano's E-TUBE PROJECT software. This B-variant kit includes both SD50 and SD300 PC link cables, making it compatible with both first and second-generation E-TUBE systems.

Highlights

• Universal E-TUBE compatibility: Includes both SD50 and SD300 PC link cables to work with all generations of Shimano Di2 and STEPS components.
• Firmware updates: Keep all Di2 and STEPS components up to date with the latest Shimano firmware releases via E-TUBE PROJECT software.
• Full diagnostics: Detect errors, check system connections, and identify current leakage with the dedicated battery consumption check function.
• Component customisation: Adjust shift mode, button assignments, and synchronised shift settings directly from your PC.
• Preset management: Read and save full system settings to a file; write identical configurations across multiple bikes in succession.
• Component recovery: Restore crashed components and rewrite corrupted firmware — the only diagnostics tool capable of connecting to individual components rather than the whole system.
• eBike unit protocol recording: Retrieve and display unit data as a report to review settings and battery status on STEPS eBike systems.

In the Box

The SM-PCE02 B-variant kit includes the PC linkage device unit, one Micro USB-to-USB cable for PC connection, one SD50-type PC link cable (for first-generation Di2 and STEPS components), and one SD300-type PC link cable (for second-generation and 12-speed Di2 and STEPS components).

How It Works

Connect the SM-PCE02 to your PC via the supplied Micro USB cable, then plug the appropriate PC link cable into the E-TUBE port of any Di2 or STEPS component. Launch Shimano E-TUBE PROJECT (downloaded free from Shimano) to access firmware update, diagnostics, customisation, and preset management functions. For best results, connect directly to a PC USB port rather than through a USB hub, as recommended by Shimano.

Compatibility & Fit

Compatible with Shimano Di2 electronic shifting (road, MTB, and gravel — including 11-speed and 12-speed systems) and all Shimano STEPS eBike drive systems. The SD50 link cable connects to first-generation E-TUBE components; the SD300 link cable connects to second-generation and current 12-speed components. Requires Windows PC with Shimano E-TUBE PROJECT software installed and appropriate USB drivers.
