In a few words, if you’re bottoming out frequently, but your sag is correctly set, add a volume spacer to reduce air chamber volume and increase the rate of progression in your suspension. Reducing volume makes your suspension firmer sooner in the travel, increasing the spring rate in the mid and end-stroke.
What does increasing axle to crown length do?
It raises the front end and in doing so slackens the head angle. The rule of thumb is for every 20mm of additional AC length you slacken the head angle by one degree. So you have effectively changed the head angle in the above example by 2 degrees.
