THE ULTIMATE TRAIL BIKE
We’re lucky to be riding during the Golden Age of mountain biking. We have access to more trails than ever, built with more diversity than ever, riders are progressing and nailing what was previously impossible, and now the new Stumpjumper EVO is evolved to meet the demands of modern riders. Delivering unprecedented control, capability and adjustability, along with unexpected climb-ability, it tames any terrain from chundery jank to progressive high speed flow and modern big hits. It’s your seat in the eye of the hurricane.And that’s good, ‘cause when shit starts flying on the trail, you’ll be zen in the middle of the mayhem
CAPABILITY AND STABILITY
Available in six style-specific sizes, the StumpjumperEVO sets the benchmark for progressive trail geometry,delivering DH capability never before found from a150mm bike alongside lively climbing manners. How? The generous cockpit gives you the room you need; centering 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 destroy the turns, float through them, or nail the inside lines. A steeper seat tube optimizes power output and puts your weight over the front while climbing.And short chainstays keep things flickable and nimble
SIZED FOR YOUR RIDING STYLE
S-Sizing is style-specific sizing, meaning that now you can choose your frame size based on something that matters (complementing your riding style) instead of something that doesn’t (your inseam). See, two riders might be the same stature, but have totally different styles. The poppy rider who flicks her bike around the trail will be even poppier on a smaller bike. The rider who plows chunder and smashes rocks at speed will plow and smash with conviction on a longer bike. Determining your size is easy; 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. But… 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 gnar? Bump up to an S4
SIX GEO SETTINGS TO MATCH STYLE AND TERRAIN
To be The Ultimate Trail Bike means to rule for any rider style in any terrain. That’s a big ask. The way we deliver is through the most adjustable geometry we’ve ever offered on a trail bike
Head angle is adjustable between 63 and 65.5-degrees via unique eccentric headset cups with three setting.So, whether you’re riding steep and deep, low-speed technical, or something in between, you can tune your EVO trailside in minutes to match the terrain
To keep your center of gravity down and thereby keep stability high, the EVO bottom bracket is always low. But now you can fine-tune BB height by 7mm by swapping the Horst link chips.
The EVO’s 160mm front travel and 150mm rear feels bottomless on big drops, supple on small bumps, devours square-edged hits, yet still pedals responsively and climbs like a lightweight. The key ingredient here is Rx Tune – your prescription for fast. Riders all, our team of engineers and technicians toiled to develop every aspect of the EVO’s suspension into an optimally performing singularity. Chassis design, telemetry, wheel rates, spring curves, custom shim-stacks, oil viscosity; front and rear suspension obsessed over, prototyped and tuned to deliver optimized and balanced performance, allowing the bike to disappear beneath you, leaving you confidently in control
The new EVO’s leverage rate is derived from the Enduro’s progressive approach. This is key in delivering small bump sensitivity, mid-stroke support, and compliant but controlled full travel when really stomping the bighits. The tuned leverage rate also makes it easier to refine the shock to match the kinematics. Bottom line,the suspension does what you need it to, so you can do what you want to do: shred.
Taking a cue from the kinematics of its big brother Enduro, the new EVO’s axle path is tailored for getting after it. The axle moves rearward in the first third of travel, and then vertically in the mid-travel before arcing to a forward trajectory toward bottom out. To break this down, the rearward path in the first portion of travel allows the wheel to “swing” back with the bump force, decreasing hangup and thereby helping to carry speed. As the bike moves deeper into its travel, where pedaling isn’t typical, the forward axle path disconnects chain forces from pedaling forces, allowing the suspension to independently compress in response to input from the trail
The SWAT door on the Stumpjumper EVO is a masterpiece of carbon fiber construction and spatial optimization. A simple pull and twist of the water bottle cage opens into a cavernous downtube storage compartment. There’s 15% more room than before; enough room to store 22oz of life giving water in an included, specifically designed bladder. Or some tubes and a rain jacket. Or folded up slices of pizza. Or multiple bananas(careful with that last one). Because we can tailor the layup of our carbon fiber, putting material where it is needed most, we can also design in this easy access storage compartment with zero compromise of the chassis strength or stiffness
Let’s just be blunt about this. Weight matters. Yes,aggressive tires are going to weigh more, and componentsyou can pummel are going to pack on the grams, but youstill gotta get that bike up the hills and when it comes toclimbing, excess mass can feel like it’s dragging you downto the center of the earth. With an S-4 frame weight pareddown to 2750 grams*, we cut no corners with the EVO; it’sthe lightest frame possible for the performance you needto dominate in the hazardous duty you’ll put it through. Wethen dressed each model in carefully spec’d componentrythat delivers maximum performance with minimal weight.EVO is light enough to get you to the top without beingcross-eyed for the downhill, and tough enough to let youget as rowdy as you want on the way down.
