Slacker, longer, lower—you've heard it a million times, but this time we mean it. A 63.5-degree head tube angle? Yeah, this thing's built to shred. But it's not just the geometry that makes it so capable. Oh, no. The Stumpjumper EVO Comp Carbon 29 has been designed with one goal—to conquer the gnarliest of trails out there, without a DH bike.

What exactly is the EVO for? EVO is for the shredders—the gnarliest trail riders who live for gravity riding. Big drops, huge kickers, rocks, roots—whatever you throw at it, the Stumpjumper EVO can handle it. EVO uses the same style-specific sizing that's featured on our Demo. This sizing lets you choose the bike that fits the way you ride—not just by the seat tube measurement like with most bikes—and it narrows things down to two sizes, S2 and S3. These are longer, lower, slacker, and have seat tube and head tube heights that allow you to choose the size that best suits your style and terrain.

Our other design goal 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 and shapes.

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.

We continued down the suspension path with a custom Rx Trail Tune on both the fork and rear shock. Suspension performance is highly dependent on frame, wheel, and rider size, so we use our Rx Tune to get each bike to land in the middle of the adjustment spectrum, and this gives you the biggest possible range to fine-tune your ride. Another focal point of the tune was matching the suspension characteristics between wheel sizes—we developed a specific Rx Tune for each platform. So, no matter what wheel size you prefer, you'll get perfectly linear suspension.

Steps were also taken to make this bike easy to live with. Threaded bottom brackets make a triumphant return, and we made room for up to a 2.8" tire. You're also free to run whatever aftermarket rear shock you want, since we're using standard metric shocks. We revamped the SWAT™ box, too, making it sleeker, lighter, and with more volume. And customization is furthered with a Flip Chip that lets you to dial-in your Stumpy to your riding style. Switch it from High to Low and it drops your bottom bracket 6mm and slackens the head tube by half-a-degree. Little details also jump out to surprise you, like a newly designed ribbed chainstay protector that makes chain slap a thing of the past and nearly silences the drivetrain. Lastly, we seriously couldn't make cable routing any easier on carbon models. Full tubes can be found throughout the carbon frame, so all you have to do is push the cable and it'll come out the other end. No more lazy loop, hidden stashes of magnets, pokey spokes, or pillows to cry in.

For the build, we've hit the perfect combination of durability and performance. SRAM NX Eagle handles shifting duties while Code R brakes are in charge of slowing you down. We then took the bomb-proof Roval Traverse rims and wrapped them with 29x2.6" Butcher GRID tires to ensure you have plenty of grip, no matter how loose the trail is.

  • With its FACT 11m full carbon frame, 29 Trail EVO geometry, and 140mm of travel, the Stumpjumper EVO has been purpose-built to shred the most gravity-defying trails.
  • FOX FLOAT DPX2 Performance has three modes for plenty of on-the-fly adjustment.
  • A FOX 36 Rhythm fork handles suspension duties up front, with stiff stanchions and plenty of adjustability.
