Rolf Aldag (born 25 August 1968) is a German former professional road bicycle racer who rode for Team Telekom from 1993 to 2005.

T-Mobile hired Aldag as sporting director after sacking Rudy Pevenage who was named in the 2006 Operación Puerto doping case.

[1] Following the team's demise, Aldag spent a year working for the World Triathlon Corporation before taking up a role as a technical link-man between Specialized Bicycle Components and Omega Pharma–Quick-Step in 2013.

[6] His confession was triggered by accusations of former Team Telekom masseur Jef d'Hont from Belgium.

In his book, of which excerpts where printed in the German political magazine Der Spiegel in April 2007, D'Hont accused members of Team Telekom of systematic and organized doping with EPO in the mid-1990s.
