Left behind the dramatic 2017 season due to a double knee surgery, the Australian rider with German heritage put professional effort and dedication to come back and to perform very well on last racing season, showing what a true professional he is, but also the love he has for this sport and the team. He is a rider who can cover many different roles as well as supporting the young up and coming riders, bringing a wealth of experience to the team.
He started his professional career in 2005 shooting immediately to prominence with a stage win at the Vuelta. Then he took five great successes in 2006 and has had strong classics campaigns since then: in 2009 coming 2nd in both the Tour of Flanders and Milano-Sanremo, besides the 7th place in Paris-Roubaix. Haussler's biggest victory was the win of Stage 13 in 2009 Tour de France. In 2015 he won the Australian National Road Race Championships.
In 2016 with IAM Cycling he took excellent results in Classics as the 6th place in Paris-Roubaix and the 7th in Milano-Sanremo. He rode the Giro d’Italia, where he was 8th in a stage. He had other top ten finishes at Tour de Pologne (twice 4th and once 7th).
