Type and length can depend on the year model. Some are straight pull, some are J-bend type. Some have paired spokes some (the more recent) do not.
Some of them have the spoke length written in fine print on a rim label, some do not and will need to be measured.
If I'm right your model should be a later one with J-bend non-paired spokes which makes them easier to rebuild with DT stainless spokes.
