Welcome to live coverage of stage 11 of the Tour de France - a short but beastly 148km ride from Albertville to La Toussuire that features four climbs including the fearsome Madeleine and Croix de Fer climbs, and the summit finish at La Toussuire.

Evans and Van Garderen catch Moinard, but the Frenchman cannot keep up with the pace of his BMC team mates and is dropped. They have 22 seconds on the yellow jersey group, which has been whittled down to about 10 riders now - including four Sky men.

Evans and Van Garderen still have Moinard further up the road too, so BMC will have three. Clever riding - but is it still too early? Remember, we have the 18km ride to the finish still up ahead. Back with the leaders, it's Europcar pair Rolland and Kern dictating the play. Scarponi has not only been dropped from the leading group, he's now off the back of the yellow jersey group, alongside Rui Costa and Rein Taaramae. Andreas Kloeden too.

Evans has now joined the white jersey Tejay van Garderen up the road. The young American had attacked a little bit earlier, paving the way. The BMC pair will now ride together and try and turn this Tour on its head.

Evans reaches Leipheimer's wheel and is combining with the American. But Sky are not concerned in the slightest, and continue riding their rhythm.

ATTACK: Cadel Evans breaks clear of the yellow jersey group. That was totally out of the blue - and just what the race was waiting for.

The lead is up to 4:05 after this fabulous ride by Christophe Kern. Team Sky still in total control of the main pack. At this rate, they're going to ride the yellow to Paris at a canter.

Lotto Belisol's Jelle Vanendert has been dropped by the yellow jersey group. That's a big-nam casualty - and a concern for Jurgen van den Broeck.

FDJ's Pierrick Fedrigo has been shelled by the yellow jersey group. The Frenchman has three stages to his name in the Tour, but he has struggled with illness and form since his last win back in 2010.

Ivan Basso and Alejandro Valverde have both been dropped. Kern is having a storming day.

Levi Leipheimer the latest of the leaders to be shed by the explosive pace of Christophe Kern. Impressive stuff from the Frenchman. He was unable to show the world his powers last year when having to withdraw from the Tour with tendinitis in the first week before the whole Voeckler-in-yellow bonanza for Europcar.

Another withdrawal for Rabobank: Australian Mark Renshaw joins Bauke Mollema in the team car. It's been a hard Tour for Renshaw, who never looked close to taking a sprint win.

Kern is driving a fast pace in the leading group. Europcar going for their second win in as many days through Rolland. The lead is 3:15 now. Back with the bunch, it's Mick Rogers on the front for Sky while Christian Knees drops back to fill up bidons for his team-mates.

Vino is struggling and has been dropped by the leading group. As has Moinard and Kadri. This climb is going to make another huge selection. We're actually on the Col du Glandon climb now, which becomes the Croix de Fer towards the summit.

The leading groups have rejoined so we now have 22 riders out in front: Moinard, Horner, Kern, Rolland, Scarponi, Marzano, Basso, Martin, Kadri, Trofimov, Ten Dam, Valverde, Kiryienka, Sorensen, Kessiakoff, Kisierlovski, Vinokourov, Leipheimer, Veltis and Weening.

Now Edvald Boasson Hagen has dropped back - his work for the day done. The yellow jersey now has Porte, Rogers, Knees and Froome. In the chasing group, it's Christophe Kern doing his best to rejoin the leading seven riders.

Quite a few riders from the initial break are being swept up by the peloton now. Koren, Bouet and Izagirre have all been caught.

The new seven-man leading group - Rolland (EUC), Kessiakoff (AST), Velits (OPQ), Trofimov (KAT), Kiryienka (MOV), Valverde (MOV), and Scarponi (LAM) - are onto the second climb of the day, the HC Col de la Croix de Fer - (2 067 m) 22.4 kilometre-long climb at 6.9%.

The leading group has passed through the intermedate sprint but there was no contested sprint from any of them. They're not after green jersey points - its the stage or mountain points that are driving these men. There will be no change in the green jersey standings today. Incidentally, Kessiakoff took the 20 points in first place.

The answer to the quiz question posed earlier is, of course, Denis Menchov: the Russian is the rider in the peloton with the most amount of podium finishes in grand tours. Menchov has five, including two Vuelta wins, one Giro win and a second and third in the Tour.

Kessiakoff and Velits are back with the other escapees now. Leipheimer and Vinokourov no longer appear to be there after that descent. Yes, they're about 15 seconds behind a new eight-man leading group that features Scarponi, Rolland, Valverde, Velits, Kiserlovski, Trofimov, Kessiakoff and Kiryienka.

Nibali must have had a mechanical issue because he's powering through the cars onto the back of the main pack.
