Don't plan on removing them when you buy them. The middle covers cannot be removed without damaging them. I was hoping I could put the long travel aero caps back on and then put those center caps back on. Once installed, these center caps cannot be removed without being damaged. The center cap is a very thin piece of metal glued to a plastic ring that snaps into a hole in the center of the wheel. Any attempt to remove it will destroy the cap. They were pretty cheap and decent looking. However, note that this is a one-time installation and you cannot use your aero caps without damaging those caps.
