Whether you're racing your heart out, training like there's no tomorrow, or riding the trail whenever you have an hour to yourself, Specialized's Stumpjumper Expert Carbon 29er is the bike to maximize every effort. Its light, stiff FACT 10m carbon frame flies up the hills, and for Evel Knievel speed on the way back down, you've got a RockShox SID 29 fork equipped with Specialized's Brain that automatically changes firmness for maximum efficiency. Lightning-quick Roval Control Carbon wheels deliver sheer speed on climbs, sprints and are ready to shred any XC course or ribbon of singletrack. A mix of Shimano XT and XTR 11-speed components handle drivetrain duties, the pairing ensures the optimal blend of durability and precision, as well as a wide-range of 22 gears. SRAM carbon cranks keep the weight down and let you spin up the steepest pitches, while Shimano supplies their sure-stopping disc brakes for premium control, and a Command Post XCP dropper post lets you get aggressive on the downs. What's more, you get a spread of Specialized's components for full singletrack dominance.
