Riders are able to gain bonus seconds by finishing on the podium in all stages - except time trials. Something that does seem somewhat unfair to former time trial specialist
Tom Dumoulin who spoke in favor of awarding the best chrono specialists as well.
This comes as a relatively surprising statement, which surged after the mountain time-trial up to Peyragudes at the Tour de France. But it's own nature, every rider races the time-trials alone and the time taken on the line is then taken into account for the overall classification. With certainty, not many would agree that bonifications make sense in the context of a time-trial, but former World Champion
Tom Dumoulin would've liked to see that when he was a pro.
