On Rails Yet Off-Road: Specialized’s Stumpjumpers Are a Biker’s Dream

Scroll through Specialized Bicycle Component’s new lineup of Stumpjumper mountain bikes and you’ll see a wide array of classifications and prices. With prices climbing from $4,400 to $9,500, the money spent on a new ride from Specialized is no joke — but neither are the bikes.

The new Stumpjumper’s rail-like riding experience epitomizes performance mountain biking. Featuring a new frame, Specialized was able lean on frame kinematics to deliver a high-quality ride experience. With bottom-out support that allows riders to smoothly land even the largest of airs, it still handles gracefully over smaller obstacles and bumps. The brand’s in-house suspension team even specifically tunes the bike to allow for a variety of ride uses without much need for adjustment.

This aspect is something professional mountain biker Kayley Burdine can’t help but enjoy.

“I love the Stumpjumper, especially for the terrain out here,” Burdine told Trucks.com, after bombing through the Santa Cruz, Calif., mountain bike trails recently. “It’s super squishy and absorbs the roots and rocks and bumps really well.”

For when the terrain changes, the Stumpjumper features a fully adjustable seat, allowing it to flow between a variety of different stop points. Since two hills (or descents) are never the same, this offers a range of ride positions, giving riders the opportunity to attack certain stretches exactly as they see fit. Though many mountain bikes offer adjustable seats, riders touted the Stumpjumper’s ability to let them decide where to let it stop.

“I’m used to [a seat] with three settings,” Bryon Dorr, an avid mountain biker, told Trucks.com, after testing the bikes. This “one will let you set it wherever you want. A couple times I wanted to go uphill, but maxed my seat all the way out. I could knock it down just a little bit and it was perfect for how I wanted to climb. It’s amazing what a difference that makes over a long day of riding.”

None of the seat mechanics would be possible without the Stumpjumper’s 1×12 SRAM gearing system. With this upgraded drivetrain, the controls on the left side of the handlebars are free to access the seat height shifter. The space isn’t needed to work a front derailleur. The drivetrain includes a chainstay protector that allows the drivetrain to operate at a whisper, as its nubs help it avoid any unnecessary slapping.

When going downhill, the Stumpjumper’s suspension and versatile seat complement its stiff frame, dramatically improving its effectiveness. Specialized made it a point to study the correlation between the positioning of a rider’s hands and feet, especially as terrain changes rapidly, to build a frame capable of delivering that on-rails feel. Put plainly, riders just point the bike where they want it to go, and that’s exactly where it’s headed.

Since some riders prefer to leave their backpacks at the staging area, the new Stumpjumper features Specialized’s  down tube storage compartment that can hold things like a multi-tool and granola bars.

Specialized’s entire lineup of Stumpjumper mountain bikes includes 18 different styles.
