S-Works Stumpjumper 27.5
2020 S-Works Stumpjumper 27.5
It’s earned glowing reviews the world over… Our light-yet-strong carbon frame delivers bump-devouring suspension and effortless control. Equipped with the best suspension, drivetrain and wheels available, the S-Works edition dishes out peerless performance.
THE ULTIMATE TRAIL BIKE
The innovative sidearm 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
Our carbon chassis melds 150mm of smooth and deep suspension with smart features, including our integrated SWAT™ box downtube storage and painless cable routing. No proprietary bullshit and a threaded bottom bracket also mean that this frame is 100% hassle free.
• One of the lightest—and most capable—trailbikes on the market.
• S-Works delivers 150mm of smooth suspension and unrivaled handling.
• Top-tier suspension courtesy of FOX FLOAT DPX2 Factory rear shock.
