Trek Superfly 6 (2014)

For the XC enthusiast on a budget, here's a good choice: the Trek Superfly 6. Sharing much of the performance of its carbon brethren, this bike features a lightweight alloy frame and RockShox Reba fork for smooth, sure handling on rough singletrack. SRAM goodies make up the drivetrain, and components from Shimano, FSA, and Bontrager finish things off.
