A late mechanical proved costly for Team Sky's Richie Porte as Nicola Boem (Bardiani-CSF) won stage 10 of the Giro d'Italia on Tuesday.
Boem was part of the breakaway which held off the charging peloton in the finale of the 200-kilometres route from Civitanova Marche to Forli.
Alberto Contador (Tinkoff-Saxo) enjoyed an uneventful day to retain the overall leader's pink jersey, with Porte's bid for the maglia rosa hindered by a mishap with around 5km to go.
The Australian, who began the day 22 seconds behind in third, suffered a late and costly mechanical, losing 47 seconds to the Spaniard to slip to fourth.
Porte now trails Contador by one minute nine seconds overall, with Fabio Aru (Astana) the nearest challenger, three seconds behind.
Mark Cavendish recorded his 10th win of the season as he took the opening stage of the Tour of California in Sacramento on Sunday evening.
The Manxman's Etixx-QuickStep team-mates controlled the front of the peloton to allow Mark Renshaw to give Cavendish the perfect lead-out in the final stretch of the 203.1km stage which started and finished in the state capital.
Cavendish edged out Tinkoff-Saxo's Peter Sagan and Jean-Pierre Drucker of BMC Racing for his sixth Tour of California stage win and the first leader's jersey of this edition.
However, there was also a major withdrawal as American Andrew Talansky (Cannondale-Garmin), who was looking to get into shape for the Tour de France, pulled out with what the team said was a combination of respiratory problems and allergies.
Once a four-man breakaway had been swept up, Etixx-QuickStep, Tinkoff-Saxo, MTN-Qhubeka and BMC battled at the front of the peloton for control.
Cavendish's team moved to the front inside the final five kilometres and held position under pressure from their rivals. With Renshaw his guide, Cavendish was able to jump off his wheel and win with relative ease.
Monday's stage is on more rolling terrain as the riders tackle 193.7km from Nevada to Lodi.
Richie Porte will front Team Sky's bid for glory at the Giro d'Italia.
The 30-year-old Australian, who has won Paris-Nice, Volta a Catalunya and Giro del Trentino this season, will lead a nine-man team during a competition which begins in San Lorenzo on May 9.
Porte's squad features the Italian duo Salvatore Puccio and Elia Viviani, alongside Bernhard Eisel, Sebastian Henao, Vasil Kiryienka, Leopold Konig, Mikel Nieve and Kanstantsin Siutsou.
Porte said: "The Giro d'Italia has been my main goal of the season. I've worked very hard through the winter and am entering the race strong, healthy and up for the challenge.
"The competition will be tough, and obviously anything can happen in a Grand Tour, but we've got a great group of riders going into the race and we are ready for it."

Briton Alex Dowsett is the new holder of the Hour Record after a successful attempt at the Manchester Velodrome.
The 26-year-old from Maldon, Essex was bidding to ride the furthest distance in 60 minutes and surpass Australian Rohan Dennis' record of 52.491 kilometres.
Dowsett recorded 52.937km to set a new margin by a significant distance.
His record may last little more than a month, though, with four-time Olympic champion and world time-trial champion Sir Bradley Wiggins making an attempt in London on June 7.

The north east venue was selected by the British Cycling board ahead of a rival bid from the Isle of Man.
The men's and women's time-trials will take place on June 23, 2016 and the road races on June 26.
British Cycling director of cycle sport Jonny Clay said: "Following an initial tender, British Cycling invited Stockton and the Isle of Man to present their final stage bids.
