FCR I will write various things about the Velocity Stack of city riding-FCR. Talk about vertical orientation and processing,etc....
I am writing from the perspective of a city rider. If you are racing oriented,run without a filter. There are many riders who like FCR who modify the FCR Velocity Stack a little. I won't write about Velocity Stacks in detail,but I will write about them roughly based on what I know. I think this blog post will be useful for those who have just made their FCR debut.
