Just ordered a DI2 equipped bike.

DI2 is totally new to me so just wanted to ask what it should come with in the box?

A charger hopefully

A charger. Wouldn’t expect anything else.

A doodad for connecting and disconnecting the cables. There is a good chance that if the battery is in the seat post it will be disconnected as might the mechs.

It might arrive flat so need charging. Worth doing a bit of reading as it will be unfamiliar. Things like the front mech stops working first if the battery goes flat. It has a crash protection mode which catches people out. How to adjust the gears. Despite me having had a few battery issues I wouldn’t go back to mechanical on a nice road bike.

Thanks guys.

I’ve not had much interested in DI2 / disc but found a great offer on a bike with it fitted. probably worth a go as it was only slightly more than the mechanical ultegra disc version.

what it should come with in the box?

A bike? Maybe some wheels?
Nothing on the spec sheet?

DI2 specific stuff smart arse.
