Questions about Shimano 105 CS-R7000/CS-HG700

Does the cassette fit on the Wahoo Kickr core? https://www.galaxus.ch/de/s3/product/wahoo-kickr-core-rollentrainer-10160003

Are the cassettes also compatible with the Dura Ace Di2 11-speed rear derailleur?

11-32?

Is the 11x30 version meant here, as you cannot select a version?

the clueless bicycle department of galaxus once again fails to make the different gradations selectable... so you order here on the off-chance !

Which gradation are we talking about here? 11-28? This is not clear from the product description.

I was already interested in this cassette in February 2019. Since the four search results you get when you search for CS-R700 don't tell you which sprocket gradation it is, I wrote to Galaxus directly. According to the answer from Galaxus, this is the one with the 11-12-13-14-16-18-20-22-25-28-32 gradation. Now the time has come when I actually want to buy the cassette and I am surprised to see that the product description is still identical for all four cassettes. It is still not clear which cassette is which. One would actually have to assume that the Galaxus employees are thinking along a bit and adjusting the description. At least I did, according to the community questions about the two cassettes. https://www.galaxus.ch/de/s3/product/shimano-cs-r7000-kassette-11-fach-11x-velokassette-9222681 and https://www.galaxus.ch/de/s3/product/shimano-cs-r7000-kassette-11-fach-11x-velokassette-9222684 I am not the only one who has had this problem. What's even worse is that two different Galaxus Community Representatives gave two different answers for the latter cassette! Hmmmm. I hope that the link from the February support reply is still correct and will just order this cassette once. Sorry if I'm being a bit nasty here. But I don't have much understanding for such things.

Is the 11-34 version also available?

what is the development of this tape? 11/12-25/28/30 ???
