Don't worry, S-Works doesn't get to have all of the fun—the new Stumpjumper Comp Carbon 27.5 features the same frame with a full 11m carbon chassis and rear-end as its older brother, but with a solid list of no-fuss components, including a SRAM NX Eagle 12-speed groupset, for an 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.

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.

The build on this Comp model comes with a list of components that deliver undeniable quality, like a 12-speed SRAM NX Eagle drivetrain, SRAM Guide R disc brakes, FOX front and rear suspension, and Roval Traverse 27.5 wheels.

  • The Stumpjumper's asymmetrical, FACT 11m carbon fiber construction is lightweight, stiff, and ready to take on the trail. It's built off our 27.5 Trail Geometry, so it's just the right amount of both capable and comfortable. And with SWAT™ integration in the down tube, a threaded BB, easy cable routing, and an all new chain silencer, it's ready for anything the trail, or you, throw at it.
  • The FOX DPS Performance rear shock features our Rx Trail Tune, ensuring that no matter the wheel or frame size, your bike is dialed-in perfectly.
  • SRAM's 12-speed NX Eagle groupset features a wide gear range that delivers climbing and descending efficiency in spades.

Great bike but value isn’t that great

I have had my stumpy for a few months now but I have some criticisms, you can pay 4500 for another bike and get a whole spec level higher, that being said this bike is reliable and has good parts, and a strong frame. The color is also very nice. If your in the market and you want to play it safe on your options, this will not disappoint

This bike is sick.

This bike is good from everything from cross country to pro lines and double black diamond bike park laps.

My One Complaint

While this is an outstanding rig, esthetically it needs to be ""finished off."" I ordered through my dealer directly from Specialized (shortage of stock due to CoVid) and when it arrived, it's not painted - but raw carbon fiber. The mismatched ""patches"" of fiber are pretty rough looking. I was hoping for a Satin finish. Bike looks like a prototype, or incomplete.

My favorite thing.

This bike is my favorite thing. I want to ride it every day! Coming off of an entry level Trek hardtail, so, really any full suspension bike would have made for a smoother ride, but after trying several different bikes, I'm not regretting taking the plunge on this one. Solid components, SWAT, lightweight, smooth, responsive, fun and sexy.

I would definitely buy this bike

Just ordered one and the 27.5+ carbon frame looks great and I'm exited to get on the trail

Yep this is it!

Sold 3 bikes to get this one. I was able to demo one for 2 weeks and knew it was the perfect bike! Ive taken it past what I thought it would handle and have been super pleased with the way this bike handles! I've owned many Specialized bikes. Evo comp, Stump comp alloy, Fuse Comp, Status, SX trail and Epic hard tail (including some road bikes) and this bike does NOT disappoint!! Thanks to All Star bikes in Cary NC! Way to make the perfect trail bike Guys!

Awesome bike, but I wish Specialized allowed customization!

This bike is an incredible fun machine. At first I thought it might be a drag uphill as I come from a lighter bike, but the stiffness made the uphill a breeze, I was even talking the whole way up steeper technical sections. When going downhill, the bike is poppy and playful. I felt in control the whole time and the wide tires where actually pretty nice and sticky when cornering or going down sand covered rocky descents. My only issue with it is that I LOVE the color (which is why I went with this one) but wasn't a fan of the components. I asked to switch components for those of a higher end model and covering the difference, but that was not possible. So, at the end it's more work and a higher cost to switch everything out I want to change. It would be awesome if we could mix and match frames & components in the future to make our dream bike!
