Stumpjumper

Don't worry, S-Works doesn't get to have all of the fun—the new Stumpjumper Comp Carbon 29 features the same frame as the S-Works, with a full 11m carbon chassis and rear-end. Only here, we've included a solid list of no-fuss components, including a SRAM NX Eagle 12-speed groupset for the everyman's budget.

Our design goal for the new Stumpjumper was simple—build the ultimate trail bike, one that feels telepathic. And it turns out that this feeling all comes down to stiffness. Think of it this way: when the frame's telling your hands one thing and your feet another, your brain gets confused with the imbalance and the bike feels unstable. In order to fix this, we had to get to work on dialing-in the materials, shapes, and the layout.

We started by creating our own mountain-specific stiffness test, and then we looked at the layout with Finite Element Analysis (FEA) to see where we could get the biggest stiffness improvements. This led to a big discovery: The Large and X-Large frames needed more front-end stiffness while the Smalls and Mediums were just fine. We were able to create a frame design that was 20% more efficient. And in the end, this proved to be one of the lightest trail frames on the market, today.

When designing the frame with the stiffness targets being a main goal, we developed a radical new sidearm design. The front-end and rear-end are connected at three points, and the sidearm helps keep all these points super stiff and connected, all while taking about 100 grams out of the rear-end. More explicitly, this minimizes frame flex when the rear suspension is active.

We continued down the suspension path with a custom Rx Trail Tune on both the fork and rear shock. Suspension performance is highly dependent on frame, wheel, and rider size, so we use our Rx Tune to get each bike to land in the middle of the adjustment spectrum, and this gives you the biggest possible range to fine-tune your ride. Another focal point of the tune was matching the suspension characteristics between wheel sizes—we developed a specific Rx Tune for each platform. So, no matter what wheel size you prefer, you'll get perfectly linear suspension.

Steps were also taken to make this bike easy to live with. Threaded bottom brackets make a triumphant return, and we made room for up to a 3.0' tire. You're also free to run whatever aftermarket rear shock you want, since we're using standard metric shocks. We revamped the SWAT™ box, too, making it sleeker, lighter, and with more volume. And customization is furthered with a Flip Chip that lets you to dial-in your Stumpy to your riding style. Switch it from High to Low and it drops your bottom bracket 6mm and slackens the head tube by half-a-degree. Little details also jump out to surprise you, like a newly designed ribbed chainstay protector that makes chain slap a thing of the past and nearly silences the drivetrain. Lastly, 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 and it'll come out the other end. No more lazy loop, hidden stashes of magnets, pokey spokes, or pillows to cry in.

The build on this Comp model comes with a list of components that deliver undeniable quality, like a 12-speed SRAM NX Eagle drivetrain, SRAM Guide R disc brakes, FOX front and rear suspension, and Roval Traverse 29 wheels.

No need to fret—we haven’t forgotten about all you alloy fans out there. In fact, the new Stumpjumper Comp Alloy 29 with 12-speed SRAM NX Eagle may be the most radically designed alloy bike ever made. For real, though. And with new tube shapes and an asymmetrical design, it's going to exceed all of your expectations of how a trail bike should ride.

If you know the history of the Stumpjumper FSR, you know that it doesn't believe in compromising. And not surprisingly, this still rings true today with the Stumpjumper FSR Expert Carbon 29. It features SRAM's workhorse one-by groupset and the no-holds-barred Guide R hydraulic disc brakes to round out a build that places an equal focus on durability and efficiency. At the frame, you'll find a FACT 9m carbon fiber chassis with an M5 alloy rear end that creates a lightweight, strong, and stiff construction. The carbon molding process also allowed us to revolutionize how you carry your trail essentials with the all-new SWAT™ Door found at the down tube. This compartment will fit a tube, a tool, and pump without rattling or compromising the structural integrity of the frame. And when you factor in our proprietary Rx Trail Tune at the shock, plus an aggressive, trail-eating geometry that features ridiculously short chainstays, a roomy top tube, a low bottom bracket, and a slacked out front end, you truly do get a bike that refuses to compromise.

• FACT 9m carbon fiber Trail Chassis with Stumpjumper FSR M5 alloy rear end blends stiffness with light weight to form the pinnacle of efficiency, while fully enclosed cable routing and an integrated SWAT™ Door create exceptional handling and zero-hassle storage.

• RockShox Pike RC 29 fork features a 15mm Maxle Stealth thru-axle and 150mm of plush travel to take on big hits and bumpy terrain with supreme confidence and efficiency.

• Roval Traverse 29 2Bliss Ready wheels provide a strong, stable platform that's built to deliver heaps of responsiveness, speed, and supreme handling.
