105 spacers on Dura-ace cassette?

    I've just noticed that the Dura-ace and Ultegra cassettes on Mrs G's and my roadbike appear to have black spacers with '105' on them, which seems a bit odd to me. I know the Dura-ace cassette was a Dura-ace cassette, as I'd bought the groupset separately and took it to the bike shop who built it onto a frame. The Ultegra groupset was provided by the same bikeshop, and they built that straight onto a frame they provided.
    I haven't yet had the chance to take either cassette off the wheel to see if it is still the right one, so I might be worryingly un-neccessarily.
    So if anyone's got a D-A or Ultegra cassette, and can see any writing on the sprocket spacers, let me know what it says! Ta.

    the spacers are just thin plastic rings. Can't imagine they'd have Dura-Ace and Ultegra variants of those. They weigh nothing

    It's not the weight of the plastic that worries me, it's whether I've really got D-A or Ultegra, which I've paid for, on there, or some-ones trying to pull a fast one by putting a 105 cassette on the bikes. I think the cassettes are coming off tonight, as Mrs G has spotted the post and won't stop worrying until it's sorted!

    I think the text is "10S" for 10-Speed rather than "105". My 10-speed Ultegra cassettes all have this printing on them.

    DA will be fairly obvious. They are titanium sprockets, mounted three at a time (for the bigger 6) to titanium spiders. Lock-ring should have Dura-Ace stamped on it too.
    PapaZita sounds right though. 10S is probably more like it
