Hello I’m currently building my first di2 bike and the rear derailleur seems very loose when I’m in the smallest ring combination. Is my chain too long? I set it up according to this video here: [https://www.youtube.com/watch?v=zauHqNIR1F0&t](https://www.youtube.com/watch?v=zauHqNIR1F0&t)
When i move the derailleur back it’s much tighter but it doesn’t do that by himself.
