Compact. Precise. Purpose-Built.
The E-OTHERS EW-SD50 Electric Wire – 350MM is a high-performance E-Tube connection cable crafted for Shimano Di2 systems, delivering seamless data transfer in a compact and versatile format. When space is tight and precision matters, this 350mm variant becomes the go-to solution for short-range connections—such as shifter-to-junction, junction-to-battery, or derailleur-to-junction wiring on smaller frame setups, TT bars, or integrated cockpit systems.

Built with premium-grade insulated copper wiring and encased in a durable, flexible polymer jacket, the EW-SD50 ensures zero signal degradation and impeccable digital communication between Di2 components. Its plug-and-play architecture simplifies integration with Shimano’s E-Tube platform, allowing for rapid installation and reconfiguration without tools. Just click into place—no cutting, soldering, or programming required.

The 350mm length is ideal for use within internal handlebar setups, compact frame geometries, and cockpit junction boxes where minimal slack is desired for clean, aero-optimized builds. It helps reduce cable clutter while maximizing data performance—an essential factor for both elite racers and meticulous builders striving for functional elegance.

Despite its size, the EW-SD50 is engineered to endure the harshest environments. From sweat-soaked indoor sessions to rain-soaked gran fondos, the weather-resistant exterior shields the wire from corrosion, impact, and mechanical stress. The result? Uninterrupted shifting accuracy, no matter where or how hard you ride.

It’s not just about connection—it’s about trusting your electronic drivetrain with every press of a button. And with the E-OTHERS EW-SD50 in 350MM, you’re trusting a cable that’s been designed to handle the demands of real-world riding, from the world tour peloton to backcountry gravel expeditions.

For technicians and bike builders, the 350mm variant streamlines cable management and unlocks creative routing options for Di2-equipped bikes. Whether you’re running wires through a stem, frame junction, or under the bar tape, this cable adds polish and performance in equal measure.

Compact in length. Unlimited in precision.
