Carbon-Ti X-Plug steerer expander is very simple and fast to install, only an 8 mm hex wrench key is required. After headset preload setting, the expander could be removed allowing more weight saving. Of course in this way you can use one expander for more bicycles. For carbon fibre steerer tubes the expander works also as reinforcement so expander removing isn't recommended.
