Hesjedal, named the Canadian Press male athlete of the year this week, is the defending Giro d'Italia winner.
"We had our strongest season in the history of the team in 2012, with our first Grand Tour win at the Giro, and we'll be looking to build on that success in 2013,” Jonathan Vaughters, CEO of Slipstream Sports which runs the cycling team, said in a statement Friday announcing the squad.
Danielson, Zabriskie and Vande Velde are serving six-month suspensions after providing information to the U.S. Anti-Doping-Agency about the use of performance-enhancing drugs on Lance Armstrong's former team.
Slipstream called the 2013 team its youngest roster ever, with new faces Rohan Dennis, Caleb Fairly, Lachlan Morton and Steele Von Hoff.
Dennis was Australia's under-23 road race and time trial national champion in 2012. A former track cyclist, he finished fifth in the 2012 Tour Down Under.
Fellow Australians Morton and Von Hoff and American Fairly are graduates of Slipstream’s developmental program.
Veteran Nick Nuyens, winner of the 2011 Tour of Flanders, also joins the team.
