Germany's Tony Martin has won a record-equalling fourth men's time-trial title at the UCI Road World Championships, while Australia's Rohan Dennis failed in his quest for redemption with a six-placed finish.
Martin matched Swiss ace Fabian Cancellara's achievement of four time-trial world titles with victory in the 40km test in Doha, Qatar, finishing in a time of 44min 42.99sec for a commanding win.
The German also won in 2011, 2012 and 2013 and finished second to Sir Bradley Wiggins in 2014.
"After taking the gold medal with the team, to win the rainbow jersey in the individual time trial is just the icing on the cake," Martin said.
"I was a bit scared by the heat at first, but having a good preparation here in Qatar helped me cope with it. I rode without any pressure, was focused only on what I had to do, and not on my rivals, and to come out on top is really incredible."
Olympic champion Cancellara was absent ahead of his imminent retirement, while Belarus's Vasil Kiryienka, the defending champion, finished second in 45mins 28.04secs and Spain's Jonathan Castroviejo was third.
The 26-year-old Dennis was hoping to erase memories of the Rio Olympics, a mechanical incident cost him a medal.
There were no equipment problems in Doha for Dennis, who finished one minute and 28 seconds behind Martin.
Fellow Australian Luke Durbridge took 18th place.
The win is a high in an otherwise disappointing season for Martin. The Etixx-Quick-Step rider had to retire injured from the Tour de France and finished 12th while riding for his country in the Olympics.
In fact, it was the Olympic result that prompted Martin to return to time trials. His win also helped Etixx-QuickStep claim the team time trial in Doha at the weekend.
"I haven't had a great year up until this point, but to win two world titles in the space of just four days makes up for everything," Martin said.
"Deep inside I knew I could become world champion. This gives me a lot of motivation for 2017."
