No matter how you do the math, Specialized's Stumpjumper FSR Comp Carbon 29 is an equation that equals fun. The light, stiff FACT 9m carbon frame goes up and down hills better than the best of them and features an integrated SWAT door in the downtube to store your gear! Out back, you've got 135mm of trail-taming FSR suspension. Up front—RockShox's Revelation devours rough terrain while asking, "What else you got?" Lightning-quick Roval wheels and slick-shifting 2 x 10-speed gearing with an XT Shadow Plus rear derailleur make up the drivetrain, while dependable Shimano brakes deliver premium control. Factor in the Specialized Command Post IRcc and you've got a genuine trail slayer that's ready to get out and do some work.
