one tip… i’m not sure if it is the same for an alfine 11, but this is definitely true for the 8.
PRACTICE TAKING THE WHEEL OFF AND REPLACING IT AT HOME!
I had the piss mercilessly (and deservedly) taken out of me for my inability to reattach the cassette join miles from home when I pinch flatted. It is very easy, once you know how, but complete witchcraft when you are covered in mud and guessing.
Oh, and you’ll need to start carting a 15mm spanner around with you to undo the nuts on your axles. I’ve got a Surly Jethro-Tule for this purpose (and for opening bottles)
