Shimano Di2 EW-SD300 E-Tube Electric Wire (12-Speed)

Genuine Shimano EW-SD300 E-Tube electric wire, the Di2 cable used on Shimano's 12-speed road and gravel groupsets. Use it to replace a damaged wire, re-route your build, or swap frames.

• Original Shimano Di2 E-Tube wire with SD300 plugs
• Slim, lightweight wire designed for clean internal routing
• Available in 900mm and 1200mm
• Colour: Black

Compatible with: Shimano 12-speed Di2 groupsets using SD300 ports, including Dura-Ace R9200 / R9250 / R9270, Ultegra R8100 / R8150 / R8170, 105 Di2 R7150 / R7170 and GRX Di2 RX825, plus other EW-SD300 E-Tube components.

⚠️ Not compatible with older 11-speed Di2 using EW-SD50 wires. Check the ports on your components before ordering.

Tip: Measure your old wire or routing path before choosing a length. A wire that's slightly long can be tucked away, but one that's too short won't reach. You'll need a Shimano TL-EW02 plug tool (or similar) to install it.
