I've got a two month old Trek/Gary Fisher Rumblefish 2 that's been missing whilst on tenth gear. Had a nosey and the rear cassette appears to be loose whilst screwed in (as per video) but when I remove the wheel it's nice and tight and going nowhere. I've tightened the two nuts that are on the dropouts and when I screw the maxle in the QR skewer doesn't feel too tight.
Does anyone have a proper user guide. Got nothing with bike and can't find anything online.

Looks to me as if there's a spacer, or similar, missing from the cassette to allow that much movement. Not sure why it wouldn't do it with the wheel removed though, that doesn't make any sense at all.As for the maxle,open the qr lever and you'll expose a 2.5mm allen bolt that you can nip up to tighten it's action.
