Evolved to meet the demands of modern riders, the Stumpjumper delivers unprecedented control, capability and adjustability, along with unexpected climb-ability. It tames any terrain from treacherous jank to progressive high-speed flow and modern big hits.
We’re lucky to be riding during the Golden Age of mountain biking. With unprecedented popularity, access to more trails than ever before and riders that are progressing and nailing what was previously impossible. The new Specialized Stumpjumper EVO is the edge you need. In the eye of the storm, you’ll be zen in the middle of the mayhem.
Control and Capability
The Stumpjumper EVO brings control and capability to every rider, every style, in every trail scenario. This bike serves up so much control, you can challenge yourself on lines you’ve never even seen before. And in those inevitable pilot-error situations, the Stumpjumper EVO is your auto-correct for blown lines and your insurance policy for misjudged hucks.
Available in six style-specific sizes, the Specialized Stumpjumper EVO sets the benchmark for progressive trail geometry, delivering DH capability never before found in a 150mm bike alongside lively climbing manners. How did Specialized achieve this? The generous cockpit gives you all the room you need. Centring you on the bike, delivering optimized traction and corner control.
The low bottom bracket, slack headtube angle and reduced fork offset keep things stable in the rough while giving you the freedom to destroy the turns and nail the inside lines. A steeper seat tube optimizes power output and puts your weight over the front while climbing. All whilst the short chainstays keep things supremely flickable and nimble.
S-Sizing – Sized for Your Riding Style
S-Sizing is style-specific sizing, meaning that now you can choose your frame size based on complementing your own personal riding style. Specialized allows you to choose your frame based on your needs, not just your inseam. Two riders might be of the same stature but have totally different styles. The poppy rider who flicks their bike around the trail will be even poppier on a smaller bike. The rider who smashes rocks at speed will plough and smash with conviction on a longer bike.
Determining your size is easy, as each of the sizes from S1 to S6 correlates to a previous size. For example, if you rode a Medium before, then S-3 will be your equivalent size. However, if you want a quicker, more nimble ride, you’d drop down to an S2. Want a bike that’s more stable at speed or in the rough? Bump up to an S4.
Adjustability–Six Geo Settings to Match Style and Terrain
Specialized set out to create The Ultimate Trail Bike, meaning the Stumpjumper has to work for any rider style in any terrain. That’s a big ask. The way they deliver is through the most adjustable geometry they’ve ever offered on a trail bike.
The Head Angle is adjustable between 63 and 65.5 degrees via unique eccentric headset cups with three settings. So, whether you’re riding steep and deep, low-speed technical, or something in between, you can tune your Stumpjumper EVO trailside in minutes to match the terrain.
To keep your centre of gravity down and thereby keep stability high, the Stumpjumper EVO bottom bracket is always low. But now you can fine-tune BB height by 7mm by swapping the Horst link chips.
As we all know, Mullets are a thing these days. Not the hairstyle, we’re talking about a mixed wheel adaptable setup (27.5” rear wheel and a 29” front). The larger front wheel provides traction and stability while opting to run a smaller rear wheel can heighten responsiveness and also give more physical riders a touch more room to get aggressive without hooking their shorts on the rear wheel. Specialized use a different, aftermarket shock link to achieve The Mullet with the Stumpjumper EVO, this is done to retain the handling, geometry and suspension characteristics that enable the rest of the package to shred so assertively.
Anyone can make a frame as stiff as the day is long, but Specialized know that’s not what feels good on the trail. To be one with the bike requires engineered compliance in the frame. They dubbed the EVO frame a “Sidearm” chassis.
That asymmetric strut that flows along the right side of the shock between the top tube and seat tube? That’s the Sidearm and it’s an integral part of the EVO’s frame, minimizing twist and allowing Specialized to deliver a very specific feel that unifies the frame from front to rear. Sidearm design not only delivers the ride quality you crave, it does it while using the absolute minimum of material. This all results in a frame that is strong, lively and exceptionally lightweight. The Sidearm chassis layout makes it light, while pedal-friendly kinematics and geometry deliver efficiency. The bottom line? Earning your turns won’t leave you wiped out, so you can shred longer.
Rider-First: The Rider-First Engineered™ process delivers the optimal balance of tuned stiffness, weight and ride quality from all six sizes, ensuring every rider experiences the same ultimate trail ride characteristics.
Specialized achieved this through extensive data acquisition of forces through every conceivable part of the frame, in every frame size, and then validated with countless hours of railing, sending, and all-around shredding.
SWAT – Be Ready for Anything
The SWAT door on the Stumpjumper EVO is a masterpiece of carbon fibre construction and spatial optimization. Simply pull and twist the water bottle cage to open a convenient and cavernous downtube storage compartment.
There’s 15% more room than before. Enough room to store 22oz of life-giving water in the included, specifically designed bladder. Or some tubes, a rain jacket and any other trail essentials. Specialized can tailor the layup of their carbon fibre, putting material where it is needed most. This means that the SWAT easy-access storage compartment has zero compromises of chassis strength or stiffness.
Roll Fast, Grip Hard
The Stumpjumper EVO comes shod with a versatile Eliminator/Butcher tyre combo. The rear Eliminator features Specialized T7 Compound, bringing durability, toughness and precise feel to this already aggressive but fast-rolling tyre. Upfront, a blocky Butcher in the super-grippy, uniquely crafted T9 Compound offers surefooted traction, rebound control and small bump damping. The ultimate pairing, it’s like being Velcroed to the trail.
Let’s be blunt: weight matters. Yes, aggressive tyres are going to weigh more, and components that can take punishment are going to pack a few grams. That said, you still gotta get that bike up the hills… and when it comes to climbing, excess mass can feel like it’s dragging you down to the centre of the earth.
With an S-4 frame weight pared down to 2750 grams*, Specialized cut no corners with the EVO – the lightest frame possible for the performance you need to dominate. Specialized then dressed each model in carefully spec’d componentry that delivers maximum performance with minimal weight. Stumpjumper EVO is light enough to get you to the top without being exhausted for the downhill and tough enough to let you get as rowdy as required on the way down.

Kinematics and Pedalling Manners
When it comes to climbing responsiveness and pedalling snap, anti-squat is your friend. And there’s a generous amount early in the EVO’s travel. This helps you put the power to the ground without unwanted pedal-induced bob, and it transforms wattage into forward and upward momentum.
As the suspension moves through its travel, the anti-squat characteristics drop below zero, and the suspension focuses on sucking up everything including dead sailoring blind hucks-to-flat.
