This is the bike that’s consistently reaped kudos from the cycling media and countless riders. Why all the accolades? Our asymmetric carbon chassis delivers a perfect blend of bump-devouring suspension and effortless control. Technically speaking, this thing rips.
THE ULTIMATE TRAIL BIKE
The innovative sidearm frame design makes a lighter, better-handling bike. By directly connecting all three mounting points of the rear-end and shock to the frame, we’ve increased both stiffness and performance over bumps. End result? Total control.
LIGHTWEIGHT, CAPABLE…AND STUNNING
The Stumpjumper carbon chassis makes for one of the lightest, and yet most capable, trail bikes anywhere. The innovative frame melds smooth and deep suspension with smart features, including our integrated SWAT™ box downtube storage and hassle-free cable routing.
• Carbon frame is lightweight, stiff, and incredibly capable.
• FOX FLOAT DPX2 Performance rear shock is supple and easy to adjust on the fly.
• Roval Traverse Carbon wheels roll up to speed quickly and are bomb proof.
