The 30-year-old Austrian rode the last three seasons at the RadioShack-Leopard team.
Rohregger posted a message on his personal Facebook page, saying that, “I want to let you know that I will stop at this point my professional cycling career and that I will focus on finishing my university studies and developing myself in 'normal' life. A big thank you to all of you for your great support during the last years. A very nice period of my life ends here and another one just begins. Lots of love and see you out there, Tommy.”
