The Stumpjumper EVO Alloy is no ordinary trail mountain bike. It is designed to tackle difficult terrain with ease. Featuring the same completely new design as its carbon counterparts, including adjustable head angle, 150mm of performance-tuned travel, S sizing adaptability and SWAT™ Door integration, in a lightweight yet robust chassis made of M5 alloy. Equipped with a worry-free SRAM GX Eagle 12-speed drivetrain, sturdy 30mm wide alloy wheels and RockShox Rx Tuned suspension, the Stumpjumper EVO Elite Alloy is ready to tackle any trail.

What do you get when you pair a 29-inch front wheel with a 27.5-inch rear wheel? The Stumpjumper EVO Elite Alloy, that's what you get. With all the traction and handling benefits of a bike equipped with 29-inch wheels, but with a smaller, more maneuverable rear wheel, this mullet setup suits a more playful and acrobatic style. It's perfect for the bike park and provides a total fun experience on the trail.

All the travel in the world is useless without proper suspension tuning and kinematics. For the new Stumpjumper EVO design, we prioritized kinematic performance. By applying the lessons learned while developing the Enduro, and then following that up with over 1,000 hours of field and suspension lab development, we not only improved the Stumpjumper's pedaling performance, but we made us more capable, agile and lively. We increased the anti-sag, so the suspension resists pumping better, and we further improved performance on right-angle impacts. Ultimately, this mountain bike rips trails, not legs.

The new Stumpjumper EVO's S sizing geometry is the most progressive we've ever designed. Long, low, slack, short offset fork, steeper seat tube angle - these are requirements for modern progressive riding. But not everyone rides the same way, which is why the geometry of the new Stumpjumper EVO is fully adjustable with six different settings. You can adjust the bottom bracket 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 mullet mode, the EVO allows you to use a 27.5-inch rear wheel paired with a 29-inch front wheel.

Frames designed specifically for each size use a size-specific approach to riding characteristics that ensures benchmark handling and impeccable performance, regardless of frame or rider size. Whether you're a young rider happily jumping on an S1, or a downhill-loving giant in need of the stretched S6, you'll experience the same riding traits - crisp cornering and balanced stiffness front and rear - at the lightest possible weight.

We introduced the SWAT™ door on the Stumpjumper in 2016, adding space IN your frame for "oh boy" necessities like pumps and spare inner tubes, and immediately making jersey pockets redundant. With the new Stumpjumper, we've increased the volume and added a SWAT™ reservoir, giving you an additional 22 oz of water storage -
