Description

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 brethrenincluding an adjustable head tube angle, 150mm of performance tuned travel, the adaptability of S-Sizing, and SWAT Door integrationin 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.

The Stumpjumper EVO Elite Alloy is built to brawl, no question. With a bullet-proof SRAM GX Eagle 12-speed drivetrain, stout 30mm-wide alloy wheels, and Rx Tuned RockShox suspension, theres no trail too rowdy.

• What do you get when you pair a 29-inch front wheel with a 27.5-inch rear wheel? The Stumpjumper EVO Elite Alloy, thats 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. Its 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, weve not only improved the pedaling performance of the Stumpjumper, but weve 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 youre a jump-happy grom riding an S1, or a DH-fiend giant in need of the lengthy S6, youll 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.
