EXPERIENCE: COMPETITIVE XC Some prefer the purist approach to offroad riding on a lightweight hardtail. They're driven to be the fastest: climbing more quickly, attacking sprints, and punishing anyone still hanging on their wheel. Whether competing on a closed race course, taking a long ride through the canyons, or blasting through a favorite local loop, competitive-focused hardtails always deliver a true connection to the ground, unparalleled efficiency and light weight, and explosive sprinting power. The Stumpjumper has been answering this need for over 25 years, and still remains the ride of choice of champions worldwide. The orginal and still the best.
