Has anyone got a good setup guide for Di2? The Canyon turned up early
Primarily what combinations can be configured, ideally I’d like to have synchro shift with left shifter going down the cassette and the right going up the cassette.
Assuming you have the bluetooth module as part of your setup, you'll be able to set it all up using the etube app from Shimano. Between the manual and the app it's all pretty self explanitory.
