The Czech federation said he died in Kamenice, near Prague. The cause of the death was not given.
Born on April 8, 1962, in Plzen, Simunek was the world youth champion in the off-road racing discipline in 1980. In 1983 and '84, he won the world championships of amateur cyclists before claiming the world title among professionals in 1991.
