The club have secured the signings of former England international Jason Swaine and Great Britain under 20 international John Bantock
Dragons head coach Chris Mellor said: "Swaine brings vast experience on the court, having performed at the highest level.
"But just as important will be the effect he has on the whole team away in terms of preparation and mind-set and educating our younger players."
Bantock hails from Canada but holds a UK passport and played 16 games for GB under-20s during the 2011-12 season.
