If you're looking for a traditional trail bike, you've come to the wrong place. Pack your stuff, say your goodbyes, and get out. But if you're on the hunt for the perfect shred sled—you know, a "trail bike" that you can take down DH trails, huck off blind drops, or plow through the rowdiest of rock gardens—you'll find yourself right at home on the Stumpjumper EVO Pro 29.

Who exactly is "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.

We started the construction 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.

We continued down the suspension path with a custom Rx Trail Tune at the 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. This way, 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 3.0" 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.

We kept the "get gnarly" motto going with the build kit of the Stumpjumper EVO Pro, spec'ing it with Fox front and rear suspension, bomb-proof Roval Traverse Carbon wheels, and a 12-speed SRAM GX Eagle groupset.

What a fun bike!

Great all arounder! Needed a bigger spring, but the shop took care of that for free and gave me the old one! To the ride- upright pedal position took some getting used to, but it is perfect for this bike. Brakes are awesome, suspension works great, climbing is a breeze with the big gear in the back. Very long wheel base, super stable, but you need to lean it a ton to rail corners. Air em down and have a blast. Drops are good but you need to get back further than you may be used to. Only wish at this price is Carbon bars.

Bici al top! Monta ogni tipo di salita e bene

Bici stupenda, monta ogni tipo di salita senza perdere energia, in discesa un mostro, un enduro a tutti gli effetti. Velocissima e scorrevolissima su ogni tipo di trail anche scassati. Stabilissima in discesa che porta a una maggiore velocit? e divertimento. Rilanci al top grazie agli ottimi ammortizzatori che se regolati bene la bici accelera sui cambi di pendenza.

Great out of the box and better with a few mod's

Where I live in Arizona it's a lot of sharp, rocky terrain. I wanted a bike that could bomb descents but still climb well. For climbing, I was a bit concerned about the slack front but it is easy to keep the front inline and has endless traction so very happy there. As I mentioned, we have a lot of rocks here so I flipped the flip-chip to the high setting and run thin composite pedals. I plan to be hitting some downhill parks and for that I wanted to increase the progression of the rear suspension. I replaced the spring with a Cane Creek Vault progressive spring 500-610. This makes the rear much more progressive with more bottoming resistance for DH but maintains the awesome plushness and traction of the coil. I also added mynesweeper foam inserts to protect the carbon rims and avoid pinch flats. They are much lighter than CushCore liners, work as good or better, install easier and are half the price. Overall, I am very happy with the bike so far. I keep thinking about what else I could upgrade but the bike works so good now I think buying more parts will only make my wallet lighter but not make the bike any better.

Fun rig, climbs fine, details below!

Don't be scared by the low BB height and slack HTA - this bike can still be ridden as a trail bike without a shuttle or lift in sight. I've climbed 5,000ft routes on this bike (with the stock coil shock) just fine. I notice I have to throw more half-crank pedal strokes in to avoid pedal strikes when climbing but it hasn't slowed me down. Pros: This build is light! The Traverse 30 wheelset feels great, and the Code RSC brakes with the spec'd 200mm rotors offer a ton of stopping power. The bike is super fun to ride, especially on steep fast trails. Cons: The coil shock paired with the linear linkage kinematics (see Pinkbike's 'Behind the Numbers' analysis) mean the rear end bottoms out more easily than other bikes out there. This means you either have to chose to run a softer spring that prioritizes small bump sensitivity, or a stiffer one to reduce bottom outs. The stock 550lb spring feels a little soft for my weight, however, I've ridden fairly large rock rolls into big g-outs and jump lines without much issue. Note there is no HSC/HSR on the spec'd DHX2. If you're considering this bike, I highly recommend going for it.

Nuova specy

Tutto perfetto. Pecxa soli il movimento centrale troppo basso... Sul tecnico roccioso e sui single di costa in alta mintagnaai tocca sempre col pedale. Specialized continua a preferire stabilit? in velocit? rispetto all'aspetto trialistico.
