In 1964 Post had his finest moment in road racing when he became the first Dutchman to win Paris-Roubaix. The race was run at top speed from the start and favourites Rik van Looy, Raymond Poulidor and Rudi Altig were caught out by the fast pace and missed the decisive break at Arras. Post’s team mate, Willy Bocklant, was in the break and sacrificed his chances by keeping the pace high for his leader. Five riders entered the velodrome at Roubaix with Post winning the sprint by beating the world champion Benoni Beheyt in the finishing straight. The high pace ensured that Post was also awarded the Ruban Jaune for the highest speed in a classic, the 265km run at 45.131 km/h. This 1964 record still stands as the fastest Paris-Roubaix although the route has altered since then.
Post was delighted with his victory, but always the businessman, his delight was increased when he realised his appearance money at the winter six-day races would be increased. In 1965 Post made his only appearance in the Tour de France but he abandoned before Paris. (He subsequently acknowledged that he had doped at the Tour de France.) His only other noteworthy result on the road came in 1967 when he finished runner-up to Eddy Merckx in La Flèche Wallonne although he had wins in smaller races. Post was voted Dutch Sportsman of the year in 1964 and Dutch cyclist of the year in 1963 and 1970.
Post won the Dutch individual pursuit championships six times between 1957 and 1963. He took 14 European track titles (mostly madison and derny races). In 1965 in Antwerp he set the derny-paced hour record of 63.783km, beating Stan Ockers' record which had stood for nine years.
In 1983 Raleigh pulled out of sponsorship and Post found a new backer in Panasonic. The success continued, this time with mainly non-Dutch riders such as Phil Anderson, Eric Vanderaerden, Viatcheslav Ekimov, Olaf Ludwig and Maurizio Fondriest. After the withdrawal of Panasonic, Post led the Histor and then Novemail teams before leaving cycling in 1995. He is ranked as the second most successful director behind Guillaume Driessens. Post returned to cycling as an adviser to the Rabobank team in 2005.
