Adding a dropper post
- Suitable 30.9 mm dropper posts with internal routing can be retrofitted
- To route a dropper post cable:
- Drive-side frame entry ports in downtube accept additional housing
- In motor area, cable routes past the motor tabs on the drive side
- Cranks, spider/chainring and motor covers need to be removed
- Motor can remain installed, although removing it makes routing easier
- Drive-side frame entry ports in downtube accept additional housing
