Hi, I recently got my bike refurbished with new casette and chain adn I now ordered a direct drive turbo tainer. However the trainer comes without a casette and I wonder if I can use my old casette on it or would that be bad for the (new) chain. 

Any advice is welcome

Thanks!

*Some* wear on the cassettes

*Some* wear on the cassettes is tolerable. 
Think about it.  Many of us will go through, say,  three chains over the life span of one cassette. I have a part worn cassette on the spare wheel I pop on on my winter bike when I use it on the turbo. It works fine.  Assuming the cassette isn’t observably worn out: 

New chain on old cassette = OK; old chain on new cassette = not OK.

It’s not ideal, but it really

It’s not ideal, but it really does depend on how worn the cassette is. You should notice pretty quickly if the cassette is worn enough to be scrap.

I presume the old cassette has the same size largest sprocket and doesn’t need  a longer chain.
