Don't worry, S-Works doesn't get to have all of the fun—the new Stumpjumper Comp Carbon 29 features the same frame as the S-Works, with a full 11m carbon chassis and rear-end. Only here, we've included a solid list of no-fuss components, including a SRAM NX Eagle 12-speed groupset for the everyman's budget.

Our design goal for the new Stumpjumper was simple—build the ultimate trail bike, one that feels telepathic. And it turns out that this feeling all comes down to stiffness. Think of it this way: when the frame's telling your hands one thing and your feet another, your brain gets confused with the imbalance and the bike feels unstable. In order to fix this, we had to get to work on dialing-in the materials, shapes, and the layout.

We started by creating our own mountain-specific stiffness test, and then we looked at the layout with Finite Element Analysis (FEA) to see where we could get the biggest stiffness improvements. This led to a big discovery: The Large and X-Large frames needed more front-end stiffness while the Smalls and Mediums were just fine. We were able to create a frame design that was 20% more efficient. And in the end, this proved to be one of the lightest trail frames on the market, today.

When designing the frame with the stiffness targets being a main goal, we developed a radical new sidearm design. The front-end and rear-end are connected at three points, and the sidearm helps keep all these points super stiff and connected, all while taking about 100 grams out of the rear-end. More explicitly, this minimizes frame flex when the rear suspension is active.

What do you get when you take an S-Works-level carbon frame and deck it out in a solid list of no-fuss components? You get this bike right here. The Stumpjumper Comp Carbon 27.5 delivers amazing performance on an everyman's budget.


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.


The Stumpjumper carbon chassis makes for one of the lightest, and yet most capable, trail bikes anywhere. The Comp Carbon melds smooth and deep suspension with smart features, including our integrated SWAT™ box downtube storage and hassle-free cable routing.


• S-Works-caliber, carbon frame is lightweight, stiff, and incredibly capable.

• FOX DPS Performance rear shock delivers perfectly-dialed rear suspension.

• NX Eagle 12-speed drivetrain gives you single-ring simplicity and gearing to spare.
