frThe Ultimate Trail Bike
Stumpjumper
The new Stumpjumper is the ultimate trail bike. Seriously, the damn thing rides like it's on rails. It's the most versatile trail bike we've ever made. And yeah, we're stoked about that, but we're even more excited about how well it's tuned to you. We've said goodbye to proprietary bullshit, focused on your needs, and made, what we feel, is the new benchmark in trail bikes.

You live to rip, but Big Corporation wants to harsh your vibe and plaster condos over the hometown trails. No way! Lucky for you, there’s a mysterious crew in your corner, bent on helping you win the big race for the future of the trails. You ready? Time to show these two-wheeled turkeys who really runs the show out here in Stumpjumper Country.

You Can't Lose
We've made three versions of the new Stumpjumper to give every kind of rider the best bike imaginable. The Short Travel (or ST) is snappy and nimble, while the Stumpjumper rides fast and planted. And for anyone that eats and sleeps gravity riding, we've brought back the EVO in all its slacked-out glory.
We pulled out all the stops to lighten and stiffen up the frame, and what we arrived at was a vastly more efficient structure with a new sidearm design. The sidearm design directly connects all three mounting points of the rear-end and shock to the frame, and this creates a significant increase in both stiffness and performance over bumps. More explicitly, frame flex has been minimized when the rear suspension is active. In CAD, we were able to put the new 3D shape against the last iteration of the Stumpjumper, and with Finite Element Analysis (FEA), we were able to prove that the new layout was 20% more efficient. At the end of all of this, we've ended up with one of the lightest trail frames on the market.
With over two decades of experience with FSR, we refined our proven design. We love it, because FSR allows us to tune every part of the suspension with the least amount of compromises. Bike suspension is a marriage between the frame kinematics and the shock, after all. And given that we have our own Suspension Team (led by the King of Suspension, Mike McAndrews), we had them working hand-in-hand with the frame engineers on the bike design from day one. Because of this union, we're now able to rely more on the frame kinematics and less on the shock damper to perfect the Stumpjumper's ride quality. The end result? The Stumpjumper is supple over small bumps, yet it possesses a firm mid-stroke and exceptional bottom-out support. This is the suspension that makes the Ultimate Trail Bike.
We're confident that female riders won't get a better tune than what's on offer, here. Female riders are typically lighter, so we adjust the volume, compression, and rebound accordingly for every frame and wheel size. The goal is for the rear shock and fork to perform the same as our men's Rx Tune at lower pressure.

The Flip Chip allows you to change the frame geometry with ease, all to support your riding style. There are two settings, High and Low, and when you "flip the chip," you effectively change the bottom bracket height by 6mm and the head tube angle by half-a-degree.
This is the best mountain bike we've ever made when it comes to customizing it however you want. All of the configurations use standard stroke and eye-to-eye metric shocks, so you won't find Shock Block anywhere. So yeah, if you want to swap shocks—be our guest. You won't have any problems from us or the Stumpjumper. We've also ditched the PF30 bottom bracket of yesteryear in favor of moving back to a threaded BB system, and both 27.5 and 29 frames can fit up to 3.0" tires, now. You'll still want to check with your fork manufacturer to make sure a high-volume tire can fit, but this should be music to everyone's ears.
We seriously couldn't make cable routing any easier on carbon models. Full tubes can be found throughout the carbon frame, so all you have to do is push the cable housing and it'll come out the other end. No more lazy loop, hidden stashes of magnets, pokey spokes, or pillows to cry in.
The new chainstay protector makes the drivetrain virtually silent, and it pretty much makes chain slap a thing of the past, too. The nubs on this protector disrupt the slap of the chain and this reduces the overall movement and sound of the chain.
The SWAT™ Down Tube Storage takes everything we loved from the last generation and makes it sleeker and lighter, while also adding 20% more volume.
