Daniel Rinner is the former Lichtensteiner pro, he rode for Vorarlberg for a while. Stefan Küng is also Lichtenstein-eligible, though represents Switzerland for fairly obvious reasons.
The biggest name in cycling history coming from Liechtenstein is Roman Hermann, a track rider, pro from 1975 to 1991, winner of 15 Sixes (2 of them with his brother Sigmund) and European Champion Madison in 1987 (+ several medals in the Euro champs Madison or Derny).
His other brother Peter was also a cyclist who took part in the 1988 Olympics in Seoul.
