Dynamic Volume Chamber air spring upgrade from SD Components. Version 2.
This is a drop-in upgrade which converts your fork air spring into a dual positive chamber with two air valves. One controls the first half of the stroke, the other controls mid stroke to bottom-out. One for small bumps. One for big bumps.
This allows complete control over the air-spring curve to give more mid stroke support while still having great small bump response.
Replaces the top-cap and spacer system on air forks. Can cause interference with Luftkappe on some RS Pike/Lyrik forks depending on travel and wheel size. Contact us to confirm.
Version 2 has a cleaner design which installs with a standard socket. The air valves are now hidden under a cap.
