I've carried spokes on 1400km and 1700km tours, but never needed to use them. Along with spokes, I carried a lockring tool, chainwhip and adjustable wrench. Kind of a waste to take such heavy things seeing as I didn't need them. This year I'm hoping to forgo the whip and lockring tool, but am curious of the need to take replacements.
I did a search, but wasn't satisfied. There was talk of flexible spare spokes and extra long spokes with homemade curves to get around the cassette side.
Do you take spare spokes on longer tours? If so, what are they?
And do you take anything to remove the cassette?
