I currently have an F8 and and F12. My criterion for selling? If I am not riding it. My friends and wife were shocked when I sold my 76 Masi GC two years ago. I bought it in 76, loved how it rode, and it sure had memories and miles but I rode it at most once a year. Now thinking of adding a gravel. I add that the F8 is now hooked up to a Kickr.
