Shimano EW-SD50 Di2 E-Tube Wire (1200mm) – Precision-Engineered for Electronic Shifting Systems

Shimano E-Tube Connectivity System

Upgrade your electronic shifting setup with Shimano’s precision-engineered E-Tube wires and connectors—the neural network of modern Di2 drivetrains. Designed specifically for seamless integration with Ultegra Di2 systems, these components utilize Shimano’s exclusive two-prong e-tube technology to deliver flawless signal transmission between shifters, derailleurs, and batteries.

Key Advantages:
– Universal Routing Flexibility: Install internally for streamlined aesthetics on carbon road bikes or externally for easy maintenance on cyclocross/gravel builds—no compromise on performance.
– Exclusive Compatibility: Optimized exclusively for current-gen Ultegra/105 Di2 systems (note: not backward-compatible with older Dura-Ace 7970 wiring).
– Robust 1200mm Length: Accommodates larger frames like endurance road bikes or XL MTBs while eliminating tension issues during cable routing.

Pro Tips:
– For internal frame installations, pair with Shimano’s Frame Grommet Kit (sold separately) to prevent abrasion and ensure waterproof integrity at entry points.
– Ideal for cyclists upgrading mechanical groupsets or workshop technicians building custom electronic integrations—saves hours versus incompatible third-party solutions.
