Cycling-Powerful Kruiswijk extends Giro lead

May 22 (Reuters) - Steven Kruiswijk blasted his rivals in the third and final Giro d'Italia time trial from Castelrotto to Alpe di Siusi as 2013 champion Vincenzo Nibali suffered a series of setbacks that left him far off the pace on Sunday. The Dutchman, riding a pink-tinged bike, extended his overall lead after finishing second to surprise stage winner Alexander Foliforov (Gazprom-Rusvelo) of Russia. Italy's Nibali had a disastrous day, switching his bike after troubles with his chain and rear derailleur gears and then being forced to push away a spectator who ran too close to him. Sunday's 10.8 km stage was almost exclusively uphill including a twisting, turning climb over nine km up Alpe di Siusi. Kruijswiyk was one of the few riders to use clip-on aerobars and by the end he had increased his overall lead to two minutes 12 seconds from Colombia's Esteban Chaves (Orica-GreenEdge) with Nibali in third 2:51 behind the leader. Colombia's Rigoberto Uran (Cannondale) slipped out of the top 10 after finishing 50th. Foliforov excelled in the moutainous conditions to post a rare success for Gazprom-Rusvelo, with team mate Sergey Firsanov coming fourth. Monday is the tour's final rest day.
