@sbk1198 thank for the clarification, I have the same understanding. However, it seems for the Ohlins Nix 22 you have to reuse the bottoming cone and top out spring.When doing fork cartridges, everything inside the fork comes out. It then gets replaced with the cartridge you're getting. Once you take out the bolt at the bottom, everything inside will come out. It's pretty simple and will make sense when you do it.
