Swapping PowerTap freehub
I'm going to be swapping groupsets between my bikes. I'm converting my PowerTap from a Campy wheel to Shimano so I can use it between 2 bikes. Has anyone swapped their PT freehubs before? Is it difficult? 'How to' suggestions?
It's going to go something like this:
Seven --> DA 7800 (training)
Orbea --> Red (racing)
Wilier --> Campy 10 ("special" riding) lol

Making a kilometer blurry
It's really really easy. Just follow the instructions. I think it takes longer to remove and replace the cassette than the freehub. Remember the order of the washers, and make sure you don't leave any behind -- it's a different configuration between Campy and shimano.
Of note, you might be able to do the whole thing without removing the cassette from either freehub. Just start by loosening the non drive side, then tap the axle through with a rubber mallet. I know for a fact you can get the assembly off w/out removing the cassette, but I'm not sure you can get the axle out of the freehub -- I think you can though.
That would be a big bonus if you could make the swap w/out pulling out the chain whip

SJ, there's always the old shimano 9 speed = campy 10 speed trick too. I'll be doing that with my PT and campy bike in a few weeks. Just need a second harness.

I recently replaced the freehub (or tried to). I thought I had a good system for remembering the order, but it was waaay past the time I am usually awake. In short, it did not go very well. Does anyone have a good way to describe it? The Saris diagram is not very helpful. Thanks in advance.
