Questions about Shimano Ultegra CS-RS8000/CS-HG800

quote from the description: "with this Shimano Ultegra CS-R8000 11-speed cassette. This cassette is made of extremely high quality and contains six common teeth." head shake

i would like to change the cassette, i have a 10x not 11x so i would like to change it with the 10x shimano.

Please correct the sprocket sizes, this can't be right with 22 teeth. Either it normally starts with 11,12,13,15,17,19,21,24,27,30,32?

I have an Ultegra CS-6500 with 9-speed 12-27, but I don't know the exact derailleur. Is this cassette compatible with it?

Why are there delivery dates here that you can never keep? I order the part and then I get the message that the delivery date is November. That's not exactly great. Of course you know that bike parts are difficult to get at the moment, but then don't write in such fantasy dates.

Have Ultegra 6800 11/28 is the changer also suitable for 11/32?

Can you confirm this cassette has 32theeth in its largest pinion? cause in the picture i can find only 28 teeth in the largest one..

"Bike area of use: mountain bike" - is that correct? I need 11-30 Ultegra for road bike.

Finding the right cassette is frustrating without labels. Do you have the Ultegra CS-R8000 11-speed with 11-34 on offer? Because mountains.

is the gradation (11-12-13-14-15-16-17-19-21-23-25T) also available?

That is still not adjusted after 9 months. I would like to order here. But can you please hire an editor who also knows something about bikes?

Does GALAXUS have the Shimano Ultegra CS-R8000 11-speed cassette with 11-32 spacing? If so, how much does it cost? Thank you very much for your feedback.

I would like to order the cassette in the 11-12-13-14-15-17-19-21-24-27-30T gradation. There are incorrect variants to choose from in the selection. This is not the case with Shimano. Can you correct this?

So the selection in the sprocket size gradation is really incomprehensible. All variants seem to have significantly more than 11 sprockets. That can't be right. Could you please correct this so that people know what they are ordering?

Ehm...... none of the selection has 11.... Pinions.... More than 16 to over 20 speeds are run here.

I have a Tacx NEO Smart 1. Firstly, this cassette also goes on the Neo Smart and secondly, my Shimano Ultegra components are approx. 9 years old. Is this cassette compatible?
