The Shimano SM-PCE02-B3 PC Linkage Device is the essential interface tool for anyone managing, servicing, or setting up Shimano Di2 electronic shifting and STEPS eBike systems. Connect your PC to any Di2 or STEPS-equipped bike to run diagnostics, update component firmware, check for wiring faults, and personalise shift and assist settings — all through Shimano's E-TUBE Project software.

Highlights

  • Full system diagnostics: Check connections, identify wiring errors, and diagnose component faults across Di2 and STEPS systems from a single device.
  • Firmware updates: Keep all Di2 and STEPS components up to date with the latest Shimano firmware releases via E-TUBE Project software.
  • Customise settings: Adjust shift timing, button assignments, eBike assist modes, and other personalised parameters to suit each rider.
  • SD50 and SD300 compatible: The B3 kit includes both a SD50 and SD300 PC link cable, covering 10/11-speed and 12-speed Di2 systems without needing an adapter.
  • Improved noise resistance: Enhanced communication circuitry reduces interference for more reliable data transfer in workshop environments.
  • Current leakage check: Built-in function detects current leakage across the wiring harness — a critical diagnostic step for eBike safety.

E-TUBE Project Integration

The SM-PCE02 connects to Shimano's E-TUBE Project Professional software via a standard Micro USB cable (included). Once connected, technicians and advanced riders can view real-time system status, update individual component firmware, map button functions, and restore non-responsive components. Shimano recommends connecting directly to a PC USB port rather than through a USB hub to ensure reliable communication.

In the Box

The SM-PCE02-B3 kit includes the PC Linkage Device unit, one Micro USB cable for PC connection, one SD50-type PC link cable for older Di2 and STEPS wiring (EW-SD50), and one SD300-type PC link cable for 12-speed Di2 systems (EW-SD300).

Compatibility & Fit

Compatible with Shimano Di2 electronic shifting systems across road, gravel, and MTB (10-speed, 11-speed, and 12-speed), and Shimano STEPS eBike drive units including the E6000, E7000, E8000, EP8, and EP801 series. Use with Shimano E-TUBE Project software (free download from bike.shimano.com). Requires a PC or Mac with a USB port. Connect directly to the PC — do not use a USB hub.
