S-Works Stumpjumper
S-Works Stumpjumper
We deliver! Just say when and how.
When we say "The Ultimate Trail Bike," we mean it—the all-new Stumpjumper is everything you could ever ask for in a trail-ripping steed. Want a bike that climbs with ease? The Stumpjumper delivers, thanks to a ground-up suspension redesign and lightest-in-class frame weight. How about something that's ready to shred when the trail turns downhill? That suspension re-design - paired with new Trail Geometry and the Rider-First Engineered™ frame’s perfect blend of stiffness and light weight - turns the Stumpjumper into an absolute monster descending. Point it where you want to go and let the party begin.
As with all of our S-Works bikes, the S-Works Stumpjumper is dressed to impress. SRAM's XX1 Eagle AXS wireless electronic groupset handles shifting duties while FOX Factory suspension delivers a magic carpet-smooth ride.
