Can I change my Solo Air fork to a Dual Position fork (or vice versa)?

You can’t change a Dual Position Air spring type to Solo Air without changing the CSU (Crown-Steerer-Upper assembly), and the air spring assembly. The Solo Air CSU has a small dimple in the stanchion which allows for air bypass when setting up the air chambers properly in the solo air system. The Dual Position Air CSU has no dimple- a dimple in this CSU would not allow the Dual Position spring to function properly by by-passing air when it shouldn’t. So, if changing from a Solo Air version to a Dual Position version and vice versa, you would need the Dual Position internals plus the corresponding CSU to make the swap.
