The stumpjumper has never been this good. We have an entirely new bike that’s, literally, the Ultimate Trail Bike. Seriously. the damn thing rides like it’s on a rail. The stumpjumper is 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. It is the new benchmark in trail bikes. So what’s so good about it?
• SIDEARM FRAME:
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
We love FSR, because it 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, 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. What does this mean for the ride? Well, it’s now supple for the small bumps, with a firm mid-stroke and exceptional bottom-out support. This is the suspension that makes the Ultimate Trail Bike.
• RX TUNE:
Our in-house Suspension Team adjusts every shock to ensure that it’s perfectly paired for the specific kinematics of your bike, so it’ll ride in the sweet spot with an ideal range of adjustability.
• WOMEN’S RX TUNE:
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 with our men’s Rx Tune at lower pressures.
All of the configurations use standard stroke and eye-to-eye metric shocks, so you won’t find Shock Block anywhere. 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.
• FLIP CHIP:
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.
• IMPROVED CABLE ROUTING:
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.
• SWAT™ DOWN TUBE STORAGE:
The new SWAT™ Down Tube Storage takes everything we loved from the last
generation and makes it sleeker and lighter, while also adding 20% more volume.
• QUIETER DRIVETRAINS:
The revolutionary new chainstay protector makes drivetrains virtually silent and pretty much makes chain slap a thing of the past.
