STUMPJUMPER EVO
The Ultimate Trail Bike
The EVO is your seat in the eye of the hurricane, delivering unprecedented control, capability and adjustability, along with unexpected climb-ability. And that’s good, ‘cause when shit starts flying on the trail, you’ll be Zen in the middle of the mayhem.
2020 PINKBIKE MOUNTAIN BIKE OF THE YEAR
Stumpjumper Evo
“. . . effortless handling and ability to excel on a wide variety of terrain are what really cemented the win, although the massive amount of storage in the down tube didn’t hurt either.”
Instant Rowdy
EVO Geo
Out of the box, the Stumpjumper EVO delivers the most capable trail geometry on the planet. And its adjustability features allow you to customize the ride to suit your style and specific terrain.
Stumpjumper EVO sets the benchmark for modern trail geometry, delivering DH capability alongside lively climbing manners. The generous cockpit centers you on the bike, optimizing 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 choose between destroying the turn, floating through it, or nailing the inside line.
Benchmark Adjustability
The Stumpjumper EVO offers six distinct geometry settings to hone its performance for any style, any terrain. The head angle can be adjusted between 63- and 65.5-degrees. Bottom bracket height can be fine-tuned up or down by 7mm. And an aftermarket shock link allows the standard 29” rear wheel to be swapped out for a 27.5” wheel, without affecting other handling dynamics. This EVO’s seamlessly integrated adjustability makes it the most adaptable trail bike ever.
With our aftermarket MulletLink, you can ride a 27.5” rear wheel to liven up responsiveness and give yourself more room to get rad without hooking your shorts on the rear wheel, all while retaining the geometry and suspension characteristics that enable the EVO to rip the way it’s meant to.
The EVO’s S-Sizing is based on what matters; rider size and style, not inseam. Six sizes, all with similar headtube lengths and standover allow you to choose the size that best suits your individual style. Smaller S-Size numbers are going to be more nimble, thanks to their shorter reach and front-center measurement, while bigger S-Sizes deliver more stability and a roomier ride.
Find Your S-Size
Determining your S-Size is easy; for example, if you rode a Medium before, then S-3 will be your equivalent size. But… if you want a more nimble ride, you’d drop down to an S2. Want a bike that’s more stable at speed? Bump up to an S4. Following are examples of three riders, all 5’8” (1.73m), who chose three different sizes.
EVO Suspension
The EVO’s 160mm front- and 150mm rear travel is supple on small bumps, devours square-edged hits, feels bottomless and plush on big drops, yet still pedals and climbs responsively. The key ingredient here is Rx Tune – your prescription for fast. Our team of trail obsessed suspension engineers and technicians toiled to develop every aspect of the EVO’s suspension into an optimally performing singularity.
Leverage Rate
Tearing a page from our award winning Enduro’s acclaimed suspension performance, the new EVO’s leverage rate delivers small bump sensitivity, mid-stroke support, and compliant but controlled full travel when stomping the big hits. The tuned leverage rate is matched by our Rx size-specific tuned shock, allowing the suspension to do what it needs to do so you can do what you want to do: shred.
EVO Chassis
Send it, Mama Bear. That’s right, not too stiff, not too soft…. this bike slaps! These days we can make a frame as stiff as the day is long, but it turns out that’s not what feels good on the trail. To be one with the bike requires engineered compliance in the frame.
Tuned Stiffness
We tuned the entire chassis – front end, rear end, and the link between them – as a single unit. This minimizes lateral and torsional deflection and delivers telepathic handling. The Sidearm strut flowing along the right side of the shock between the top tube and seat tube is key to reducing unwanted flex, and allows us to deliver a very specific feel that unifies the ride from front to rear.
Our 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.
SWAT. Ready For Anything.
The SWAT door is a masterpiece of carbon fiber construction and spatial optimization. There’s 15% more room for your “stuff” than before – such as the included 22 oz / 650 mL SWATer bladder.
Instant Rowdy,
All Metal
Meet the fully adjustable, high performance, alloy frame rendering of the award winning Stumpy EVO; delivering unmatched control, capability and ride quality in a tough-as-nails aluminum frame. Full featured, premium performance with zero compromises, the alloy Stumpy EVO is a bleeding edge trail machine that will enhance your ride regardless of the terrain or your velocity. The ultimate rider’s ride. Load more metal into your playlist, and turn it up loud.
The graphics on the EVOs is inspired by the mountainous terrain that we love to ride. We wanted to capture the way light plays in nature; how it can cast the mountains in jagged relief but also soften and smooth depending on how the light hits, illuminating both hard lines and subtle fades. Multiple coats of ultra high quality paint result in a finish so smooth and deep it feels like you could dive into it.
EVO Creators
Being tasked with creating the rippingest trail bike we’ve ever made is no small feat. Steve Saletnik, Brian Robinson, Kayla Clarot, Jamie Stafford, Will Chan, Fred Chiu, Chance Ferro, and more than a dozen others dug into every aspect of handling dynamics, chassis stiffness, suspension kinematics, and design to do exactly that.
