This issue we are going to take you through how to install volume spacers into you RockShox or Fox fork.
Volume spacers are designed to make the air chamber smaller. This makes the fork ramp up more quicly making it less likely to bottom out. With the fork setup to the correct sag, and you are still finding that you are bottoming out too easily or too frequently, you could benefit from adding a spacer or two. Using a setup aid like a ShockWiz will also tell you if you need to add or remove any.
