Trouble shifting with new utegra/mavic wheelset

I have a Trek 2300 and 3 wheelsets:
1) Rolf Vector Comps and a 9 speed 12-15 cassette
2) An 8 speed dura Ace wheel that I use on the trainer with a 9 speed
12-23
3) A brand new Mavic Open Pro laced to Ultegra 9 speed Hubs - with a
12-25 cassette

I can use the first two wheels without adjusting the derailleur
The Dura Ace wheel fine with 3 turns of the barrel adjuster
BUT
When I install the Ultegra mavic Wheel:
The chain brushes the spokes in the 39-25 and will not engage in the
53-12 (it will engage in the 39-12 though)
The other the 7 inner gears work fine -

Is there a way to make the ultegra/mavic wheel "compatible' with the
other two without adjusting the rear derailleur?

All of the cassettes are either brand new or slightly used - the chain
has but a few hundred miles on it -
Thanks

If I'm reading this correctly, it sounds like your Ultegra hub is bringing
the cassette just a bit closer to the frame (and derailleur) than the other
two wheels. If that's the case, then you need a very thin washer, maybe
..5mm, between the derailleur-side locknut and cone. No need to worry about
removing space from the other side, as this isn't enough to worry about.
It's possible, though, that there already is such a spacer on the opposite
side, and all you have to do is remove it and put it on the derailleur side
and all will be well.

Perhaps, put a 1 mm spacer on before the cassette.

Thanks for the help!
The spacer worked fine!
