The replacement core seems to work. It was as easy as shown on all the videos. I havens't put it on the rim into the tire yet. Please stop bothering me with requests for reviews unless you are going to pay me for them.

I am so happy, because I get the Kinetic Pro X wheels, in my last visit to NYC. I did not remember to get the tires and tubes that I would need. When I arrive to my country, I ask for tires and tubes, and here I found the schwalbe v6, and now, I have my tern d8 ready! Thank you!
