Does anyone know if Fulcrum R0-123 XDR freehub is compatible with my Fulcrum Speed 40c rear wheel? The wheel is currenty running Shimano HG freehub.

The 40c looks to use the RS-005 freehub... whish uses a 17mm axle. wheels that offer the XDR use the same campy freehub and offer R0-123 XDR and R0-126 XDRv2

R0-123 have one RS-011 (6803) and one RP9-009 (17287) bearings.
R0-126 (XDR - v2) have two RS-011 bearings.
