2021 S-Works Stumpjumper

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.

21 Stumpjumper best Ever

My 3rd S Works SJumper and by far the best bike. Climbing fast than my 16 w 4 bar Horst suspension. 29 in wheels gobble up terrain. Low CG makes it corner fast. The bike is a beast. Really like the BT shifting and dropper post. Was not sure I would like the battery and Bluetooth, but I would not go back to cables. Outstanding handling on SE trails.

Would Recommend?
Yes!

It's not an enduro

I have a 2020 enduro and 2018 Levo SL. It took some fiddling with sag and volume spacers but this thing is a blast. Sizing is very important with the newer geo. I'm 5'7 right between S and M for almost every bike brand out there. My enduro is S2 and I bought this in S2 as well. 50mm stem with 30mm rise bars. It's a very light trail bike that hasn't talked back when I asked it to do things at speeds it wasn't designed for. On sundays i ride to the trails from my house (30 minutes) then pedal around the front range. Love it. I disagree with the reviews about the pedal bob. It bobs but it doesn't hurt the efficiency.
