Shimano Di2 E-Tube EW-AD305 Conversion Adapter Info
The Shimano Di2 E-Tube EW-AD305 Conversion Adapter bridges the gap between two generations of Di2 wiring — an SD50 port on one side, an SD300 port on the other. If you're running an older SD50-based system and want to integrate a newer SD300 component, this small adapter handles the connection cleanly without replacing your existing wiring.
It's a straightforward solution for riders upgrading incrementally or mixing groupset generations. One adapter, no rewiring headaches.
- Compatibility: SD50 to SD300 conversion
- Works within Shimano Di2 E-Tube systems
- Single SKU: IEWAD305
