Tejay van Garderen led BMC Racing to gold in the UCI Road World Championship men's team trial on a wet day in Ponferrada.
Tough conditions on the 57.12-kilometre course made all 29 teams cautious in their approach to the race but BMC were able to finish 31.84 seconds clear of their nearest rivals Orica GreenEDGE.
Team Sky, including Bradley Wiggins, had hoped to take a podium position on Sunday but they were pushed down to fourth as Omega Pharma-Quick Step (OPQS) snatched third place on the final run.
Fabian Cancellara's Trek Factory Racing were the early pacesetters as they crossed the line in one hour four minutes 31.32 seconds and although Cannondale and Garmin-Sharp failed to beat them their lead was soon over.
BMC put together a very fast pace on the course and were quickest in the third time check before stopping the clock over a second faster than Trek.
Team Sky began their challenge well but began to lose time in the final section and had to settle for fourth, while Tinkoff-Saxo and Katusha finished further down the standings.
After Sky had finished it was left to OPQS and Orica GreenEDGE to try and beat BMC but neither were able to do so as the weather saw them slow down.
Orica push hard but could only claim second place in one hour four minutes 1.69secs, while OPQS had to settle for bronze.
In the women's event, Specialized-lululemon took gold for the third successive world championships ahead of Orica-AIS.
The team of Chantal Blaak, Lisa Brennauer, Karol-Ann Canuel, Carmen Small, Evelyn Stevens, Trixi Worrack produced a winning time of 43minutes 33.35seconds to take the title by one minute 17secs.
Optum thought they had done enough to secure a medal as they went quickest late on but they had to watch as Lululemon, Orica and Astana came through to take the podium positions.
One team who failed to test the top three despite being well-backed to do well was Rabo Liv, the Dutch group losing riders along the route before the final three crashed near the finishing straight.
