No-nonsense, unadulterated speed—that's what our S-Works Stumpjumper Di2 brings to the table. It's made from our finest carbon fiber, and it's built off of our revolutionary XC 29 Geometry for explosive power, incredible climbing prowess, and nimble handling. At the rear, the hardtail design with razor thin seatstays blends maximum pedaling efficiency with added compliance. Add to this our Brain technology at the RockShox RS-1 fork that differentiates between rider and trail input to stay firm under effort and plush over bumps, and you have a bike that sacrifices nothing in its pursuit of speed.
To provide the optimal blend of stiffness, light weight, and strength, we constructed the frame from our FACT 11m carbon fiber. And when combined with our XC 29 Geometry, the Stumpjumper is guaranteed to deliver uncompromising, blistering speed come race day—no matter the course.
RockShox RS-1 Brain fork is arguably the most sought-after fork in XC racing. Compared to a traditional fork, its inverted design creates a carbon fiber upper that provides superior stiffness, while behaving with more sensitivity to small bumps and more control over larger hits. And with Brain technology, these characteristics are amplified and even more efficient. It also includes our Spike Valve technology that minimizes yaw in cornering, while providing maximum travel in high velocity impacts.
An S-Works FACT carbon seatpost features a lightweight construction and a 27.2mm diameter for superb vertical compliance over rough terrain.
