Di2 E-Tube Wire 1200mm for Shimano 12-Speed E-Bike & Road Drivetrains

Description:

The Shimano EW-SD300 Di2 e-Tube Wire (1200mm) is part of Shimano's next-generation wiring system for 12-speed Di2 and eBike drivetrains. Lighter and thinner than the previous SD50 models, the SD300 wires deliver faster data transmission, improved power efficiency, and easier internal routing. This version is ideal for longer frame applications where extended cable length is needed, such as internally routed time trial or eMTB setups.

Built for compatibility with Shimano Dura-Ace R9250, Ultegra R8150, EP8/EP800, and STePS systems, the SD300 connectors are not directly backward-compatible with first-generation Di2 components. The compact plug and cable design also allow for more streamlined electronic components and integration into tighter frame geometries.

Product Features:

• 2nd Generation Di2 Wire: Supports Shimano's latest 12-speed Di2 and EP8/EP800 eBike systems.
• Higher Data and Power Transfer: Smaller profile cable delivers faster performance and more efficient operation.
• Internal or External Routing: Versatile design suitable for both road and eBike builds.
• Tool Required: Use of TL-EW300 plug tool is recommended to protect connector integrity during installation.
• Future-Ready: Smaller wire profile enables smaller and lighter electronic components with future expansion potential.
