Peter Sagan's road racing resume is impeccable.

A fan favorite in cycling, Sagan won three stages at the Tour de France. He clinched the best sprinter's green jersey for the fifth consecutive time. He's the defending world champion.

But in Rio De Janeiro for the Summer Olympics, Sagan is shifting gears to mountain biking, fulfilling a dream. He's a former world junior champion in the discipline.



Sagan is also a realist about his chances. Here's a sample of some of his modest answers at a news conference on Tuesday: 

_On his expectations:

"I don't hope for anything. I have not raced mountain bike in seven years. A lot of things have changed. I'm here for more personal (reasons). I want to try. I don't expect nothing big. I will give the maximum for sure."

_On returning to the mountain bike:

"Technically, I am not bad. I am not here to lose. Can I win? If I lose, I am not disappointed. If I win, it's so good. I'm here for a result. I'm here to give my best."

_More on his chances in the Olympic race on Sunday:

"I'm not here for the results ... I am here to give my best. We will see what's going to happen. I don't know."

Switzerland's Nino Schurter and France's Julien Absalon are the top favorites.
