When performance is electric, precision is everything.
The E-OTHERS EW-SD50 Electric Wire in 1000mm length is engineered for cyclists and technicians who demand seamless communication between components in Shimano Di2 electronic shifting systems. As the connective tissue of your digital drivetrain, this E-Tube wire is far more than a cable—it’s the neural pathway of modern cycling intelligence.

Crafted with uncompromising attention to detail, the EW-SD50 ensures instantaneous data transfer and absolute signal integrity, linking shifters, derailleurs, junction boxes, and batteries into one cohesive, finely tuned system. Its proprietary construction uses high-grade insulated copper conductors wrapped in a resilient polymer housing that resists kinks, abrasions, and environmental interference. This results in zero-lag performance, even in the most extreme conditions—mud-caked cyclocross courses, scorching asphalt sprints, or alpine descents in freezing rain.

At 1000mm, this wire length is a versatile solution ideal for full-length downtube routing, internally wired aero frames, or oversized gravel bikes that demand extra span. It’s long enough to reach between battery mounts and junction ports, or from bottom brackets to derailleurs on larger frames—all while maintaining a clean, integrated aesthetic. The compact, plug-and-play connectors at both ends are Di2 E-Tube compatible, allowing tool-less installation and easy upgrades across current-generation systems.

What truly sets the EW-SD50 apart is its zero-compromise reliability. Designed to maintain stable electrical contact through thousands of shifts, bumps, and vibrations, this wire thrives under the physical demands of racing and daily training. It safeguards your ride’s digital nervous system—no misfires, no dropouts, just flawless execution at the push of a button.

For professional mechanics, the EW-SD50 also brings workshop efficiency. Its standardized 1000mm format fits most large-frame layouts without guesswork, while the resilient coating ensures safe routing through frame channels, under tape, or along chainstays. In a world where millimeters count, this wire delivers precision measured in milliseconds.

Whether you’re assembling a high-performance time trial machine, rebuilding a gravel Di2 adventure rig, or retrofitting a road bike with cutting-edge shifting, the E-OTHERS EW-SD50 1000MM Electric Wire is the link that makes it all function—flawlessly, quietly, instantly.
