Cadel Evans's BMC team produced a disappointing team time trial in Nice to see the Australia lose nearly 30 seconds to his Tour de France rivals.
The simple analysis is that we weren't fast enough.
Evans, who was ninth at the beginning of the day, now sits in 28th, 26 seconds behind race leader Simon Gerrans (Orica-GreenEDGE) after BMC finished ninth.
"Of course it's important," Evans told reporters after the stage.
"You look to gain every second in this Tour and losing a lot of seconds certainly isn't what I hoped for, or what I expected but we will have to go back and look at why and go on from here."
"The simple analysis is that we weren't fast enough."
Tour favourite Chris Froome (Sky) is just three seconds off the overall lead with Alberto Contador (Saxo-Tinkoff) a further six seconds back after four stages.
A long way off our best TTT performance. We HAVE to improve there. Congratulations to my OGE compatriots; pipping the World Champs! #tdf— Cadel Evans (@CadelOfficial) July 2, 2013
The 2011 Tour winner identifies the Stage 11 time trial in Mont-Saint-Michel as his best chance to make up lost time.
"The individual time trial is going to count for a lot but we are still a way off there. It's going to be difficult.
"I would have preferred to concede zero seconds, or maybe even make some seconds today. We have been put on the back foot, now we are going to have to see what opportunities come our way."
"We wanted to make a top five result and to lose a little less time on the big leaders for the general classification," said BMC Directeur Sportif John Lelangue said.
"So it was a little bit of disappointment with all the work we have done. We know that this can happen on such a fast parcours, even if it is such a short distance. At least we are still there and we know it is a long way to go to Paris."
