Pro bike: Timmy Duggan's Specialized S-Works Tarmac

US national champion Timmy Duggan will soon be defending his American road title, but first he will be racing the Amgen Tour of California beginning this weekend. The Team Saxo Tinkoff rider recently returned to racing at the Tour of Turkey following a nasty crash at the Tour Down Under that resulted in a broken tibia and collarbone. He spent two weeks at home in Nederland, Colorado, for some recharging and altitude training ahead of California. While BikeRadar often profiles pros' race machines, here we take a look at the training bike that Duggan, like most pros, uses away from the races.
