Good afternoon and a very warm welcome to today's extremely important individual time-trial at Penafiel.

Provisional overall standings: 1. NIBALI, Vincenzo (Liquigas - Doimo) 71h 19' 49"; 2. MOSQUERA MIGUEZ, Ezequiel (Xacobeo - Galicia) +39"; 3. VELITS, Peter (HTC - Columbia) + 2' 00"; 4. SCHLECK, Fränk (Saxo Bank) + 3' 44"; 5. RODRIGUEZ OLIVER, Joaquin (Katusha) + 3' 45"

Final stage standings: 1. VELITS, Peter (HTC - Columbia) 52' 43"; 2. MENCHOV, Denis (Rabobank) + 12"; 3. CANCELLARA, Fabian (Saxo Bank) +37"; 4. LARSSON, Gustav Erik (Saxo Bank) +50"; 5. SANCHEZ GIL, Luis Leon (Caisse d'Epargne)+ 1' 03"

Peter Velits claims an improbable victory with Denis Menchov second and Fabian Cancellara third.

Rodriguez is getting great support as he continues towards the line. Here he comes!!! He comes home in 56m 55s. That's 6m 12s on Velits. What a stage.

Nibali's time has passed and Rodriguez is still on the road and long way from home. Oh dear, oh dear.

Rodriguez powers along but you can see he's a long way from the finish. He may lose his place on the podium tonight. He may be as much as 4m down on Nibali but I'll have that confirmed.

What a great time trial this has been. Seriously, the drama and surprises have been great to watch...Nibali approaches the line...54m 38s. The gap to Mosquera has increased slightly. It's all down to Rodriguez - how much time will he lose today?

Mosquera is on his way...54m 56s. Now that's a gutsy ride. It'll be interesting to his time to Nibali now. Only Nibali and Rogriguez to come home.

The final few riders are beginning the last kilometres. He comes Frank Schleck at 56m 38s. His gap to Nicolas Roche is down to 26s.

"@#$%?! Where did Velits come from?" says George - No idea George. He trailed by more than a minute after 31km and thrn turned on the boosters. Will there be more drama? The course is clearly getting faster.

Roche crosses the line at 3m 29s down. A good ride but that ride by Velits has blown the GC wide open.

Rodriguez crosses the 31km check at 5m 27s down. He's had a nightmare. Peter Velits currently sits fourth. Rodriguez third and Mosquera second. Nibali is our leader on the road by around 30s.

I don't believe it!!! Peter Velits has knocked 12 seconds off Menchov's time - 52m 40s. That has come from nowhere. He was 1m 13s down on Cancellara and then flew for the final 15km.

Mosquera only gave up 2m 45s to Cancellara's time after 31km time.

Nicolas Roche is through 31km 3m 22s down.

Mosquera appears to be heading towards second place. Sastre comes over 1m 35s down. A pretty good final 15km from the Spaniard.

So Nibali is our leader on the road. Denis Menchov is our leader at the finish. I wonder what damage Nibali could have done if he hadn't been forced to change his bike?

Luis Sanchez comes in 51s behind Menchov - the fourth fastest time today.

Nibali is motoring along now. After 15km he leads the main contenders. Roche has taken back half the gap between him and Frank Schleck.

Vladimir Karpets of Katusha comes in 9th overall after a fine ride.
