Contador and Sagan head Tinkoff-Saxo's Tour de France squad

Alberto Contador has been provided a number of helpers in the mountains at the 2015 Tour de France, but Tinkoff-Saxo insist they will help Peter Sagan towards stage victories as well.

Contador is bidding to become the first cyclist since Marco Pantani in 1998 to win the Giro d'Italia/Tour de France double and can count on the likes of Ivan Basso and Roman Kreuziger to help him achieve his second Grand Tour win of the year.

Last year's King of the Mountains Rafal Majka returns to the Tour and will also be on hand to support his team leader in the mountains.

Tinkoff-Saxo sports director Steven de Jongh says the team will help Sagan to stage victories when the situation allows, with Daniele Bennati an able lead-out man.
