The Vuelta begins on Saturday with a team time trial in Nîmes. In total, there are nine summit finishes, which could favour the Spaniards cavalier and aggressive riding style should be choose to attack.
The bike, which was given to him at the Trek-Segafredo team presentation, has a unique paint scheme which includes references to all the major races he has won, including all three Grand Tours and countless shorter stage races.
In 2008, Contador also won both the Vuelta and the Giro d'Italia. He later won the Giro again in 2015 and the Vuelta twice more in 2012 and 2015. Such a formidable palmarès firmly sets the Spaniard in the sport's top riders, which Trek says this bike is supposed to celebrate.

"I got my first big results on a Trek bike, of which my first Tour de France in 2007 really stands out, and it will also be the bike on which I say goodbye to the grand tours and to my professional career, which has a big sentimental value for me."
Contador first won the Tour de France in 2007 with his Discovery Channel team, before moving to Astana in 2009 and winning it again.
Commenting on his new bike, Contador said: "to get this new bike is a big surprise for me and I am really happy to be able to ride my last Vuelta on it.
Ultimately, Contador says that "I believe it’s a bike that reflects me and my career completely, and I think it's one the fans will also embrace."
Contador's personal slogan 'querer es poder' (where there's a will, there's a way) is emblazoned on the bike.
