Franciscus ("Frans") Albertus Antonius Johannes Maassen is a directeur sportif. He was a professional road racing cyclist between 1987 and 1995. He completed seven Tour de France stage races, including the 1990 Tour de France where he was involved in the Stage 1 breakaway that caused the rest of the race to be the most surprising Tour in over a decade. He was the only one of the four breakaway riders not to wear the maillot jaune, but he won the stage. He twice won the Tour of Belgium, and won the 1994 Tour de Luxembourg.

The 1990 Tour de France was the 77th edition of the Tour de France, one of cycling's Grand Tours. It took place between 30 June and 22 July 1990. The 3,403.8 km (2,115.0 mi) race consisted of 21 stages and a prologue. American Greg LeMond (Z–Tomasso) repeated his 1989 victory in the general classification, ahead of Claudio Chiappucci and Erik Breukink (PDM–Concorde–Ultima) in second and third place respectively.
