Mimi, are you talking YOU build the bike at home or a shop build it? A gruppo is typically a set "group" of stuff and you should check the manufacterer's site for the item list.

If you are building it at home there is a ton more stuff. Headset, cables, housing, ferrules, quick releases, cable donuts, bar tape, cable ends, power link (if desired), bottle cages, seatpost clamp, rim strips or plugs, to start.
