Let's get something clear, the Stumpjumper EVO Alloy isn't a "normal" trail bike. It's built to get gnarly, plain and simple. Featuring the same all-new design as its carbon brethren—including an adjustable head tube angle, 150mm of performance tuned travel, the adaptability of S-Sizing, and SWAT™ Door integration—in a lightweight yet tough M5 Alloy chassis, you're going to be able to bomb down trails that you thought you couldn't touch without a full-blown DH rig.

Spec’d with a no-fuss SRAM NX Eagle 12-speed drivetrain, bomber 30mm-wide alloy wheels, and plush Fox FLOAT Performance suspension, there’s no question the Stumpjumper EVO Comp Alloy is dressed to shred.

  • What do you get when you pair a 29-inch front wheel with a 27.5-inch rear wheel? The Stumpjumper EVO Comp Alloy, that’s what. With all of the traction and handling benefits of a 29er, but with a smaller, more maneuverable rear wheel, this mullet setup suits a more jibby, playful style. It’s right at home at the bike park, and is a total blast to cut loose with on the trail.

  • All the travel in the world is useless without the proper shock tuning and kinematics. For the new Stumpjumper EVO design, we prioritized kinematic performance. Applying lessons learned while developing the Enduro, then following that with more than 1,000 hours of field and suspension lab development, we’ve not only improved the pedaling performance of the Stumpjumper, but we’ve made it more capable, agile, and lively. We increased anti-squat, so the suspension better resists pedal bob, and we further improved bump performance on square-edge hits. Bottom line? This thing shreds trails, not legs.

  • The S-Sizing geometry of the new Stumpjumper EVO is our most progressive yet. Long, low, slack, short offset fork, steeper seat tube angle – these are requirements for modern progressive riding. But not everyone jibs the same way, which is why the geo on the new Stumpjumper EVO is fully adjustable with six different settings. You can adjust the BB height by 10mm, you can adjust your head angle by two-degrees, and you can make these adjustments independently of each other. Finally, if you want to go full-party mullet-mode, the EVO lets you run a 27.5-inch rear wheel mated with a 29-inch front.

  • Rider-First Engineered™ frames use a size-specific approach to ride characteristics that ensures benchmark handling and flawless performance, regardless of frame or rider size. Whether you’re a jump-happy grom riding an S1, or a DH-fiend giant in need of the lengthy S6, you’ll experience the same ride traits – rail-sharp cornering and balanced front and rear stiffness – at the lightest-possible weight.

  • We introduced the SWAT™ door on the Stumpjumper in 2016, adding room IN your frame for those “oh sh**t” necessities like pumps and spare tubes, and immediately rendering jersey pockets redundant. With the new Stumpjumper, we have increased the volume and added a SWAT™ Bladder, giving you an extra 22oz of water storage – the same size as a small water bottle – hidden in your downtube.

Dream bike

Bought this bike as my first from specialized, and what a bike. Incredible for fitness riding, climbs, technical, drops, jumps, gaps and loam. Flies in fact. Definitely recommend. Always getting complimented!

Progress Guaranteed

The bike is good at everything that is asked if it. Steep, technical descents become easy with the headset that can swapped around. The suspension just deletes rocks and the bike just overall performs well. This bike punches well above its weight. One gripe I have is with the rear hub that detonated on me after 12 rides and less than 100 km. The dealer says it has been a known issue, so the wheels will need upgrading to make this bike an absolute beast.

Great all rounder

Replaced my Trek Fuel Ex with this bike. Didn’t realise it was a mullet but really glad I made that mistake. Such a fun and capable bike. Climbs as well as the Fuel Ex but really comes alive downhill.

Absolute dream

I purchased this bike during an amazing sale. Immediately put my Roval Traverse 27.5 (38mm inner) carbon wheels on. Running 2.8 tyres makes this bike super fast, smooth and confidence inspiring. The combination of wheels, tyres and the fantastic suspension makes this a ripper of a bike. Absolutely love it.

Ótima opção

Bike com uma geometria incrível. Tenho 1,78 e comprei no tamanho S4 Possui uma geometria muito bem ajustada. Porém o grupo Sram NX deixa a desejar. Substitui o grupo completo para um grupo shimano SLX e troquei por freios Saint Shimano também. Ficou perfeita e extremamente confiável.
