Di2 Parts
This collection helps identify electronic-system cable and connection needs. It may also contain STEPS motor covers or speed sensors serving different functions. Assess every part by exact model code; similar-looking electronic connections alone do not establish compatibility.

Choose electronics for their intended system
Record control, derailleur, battery and junction codes. Cable length and frame routing matter alongside cable type. Check junction port count and supported system. STEPS covers or sensors differ from Di2 shifting connectors and need motor and control-system details. Determine cable length along the actual route between connections; frame size labels alone provide insufficient measurements.
- Compare generation and manufacturer compatibility.
- Read cable end type and required length.
- Check whether sensor packages include accessories such as magnets.
Are all Di2 cables interchangeable?
No. Connection standards and supported components vary by model. Match exact codes.
Is a speed sensor alone a complete installation?
Check contents and system requirements. Magnets or fittings may be separate; use the description and official service information to identify required parts.
