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. - The Stumpjumper's asymmetrical, FACT 11m carbon fiber construction is lightweight, stiff, and ready to take on the trail. It's built off our 29 Trail Geometry, so it's just the right amount of both capable and comfortable. And with SWAT integration in the down tube, a threaded BB, easy cable routing, and an all-new chain silencer, it's ready for anything the trail, or you, throw at it. - The FOX DPS Performance rear shock features our Rx Trail Tune, ensuring that no matter the wheel or frame size, your bike is dialed-in perfectly. - SRAM's 12-speed NX Eagle groupset features a wide gear range that delivers climbing and descending efficiency in spades.
That spot where the bike path turns from concrete to dirt? The Pitch Sport is made to explore beyond, with a sturdy aluminum frame, smooth-riding front suspension, grippy tires for loose surfaces, and sure-stopping hydraulic disc brakes to keep you under control. Strong, sensitive type Old-school strongmen have nothing on our A1 Premium Aluminum frame. But the Pitch Sport is in touch with its feelings too, offering a ride that's as comfortable as it is durable, thanks to a lightweight proprietary alloy and Sport Trail 27.5 Geometry for sure handling. Size-specific suspension It's not enough to offer quality suspension like the coil-sprung SR SunTour XCT 30 fork on the Pitch Sport. We also custom-design travel based on frame size to keep the geometry and ride quality consistent over all sizes. Lockout limits annoying bobbing on smooth terrain. Sweet spot wheels Why 27.5-inch wheels exactly, not 27 or 28? It's a happy medium which offers most of the benefits of the older 26-inch size, like light weight and agility, with those of the newer, oversize 29er version, like fast-rolling efficiency and easy roll over obstacles. Value and performance The 24-speed Shimano drivetrain gives you the right gear, anytime. A long-lasting, rust-resistant KMC chain offers quiet, sure shifting. Grippy Ground Control Sport tires feature Flak Jacket flat protection. - The heart of the Pitch Sport is the Sport Trail 27.5 Geometry, which features a roomy cockpit to keep your center of gravity securely between the wheels for control, and a slacker head angle designed for more stable steering. - The key to mountain biking is confidence, which starts with knowing you're in control. Thanks to the Shimano hydraulic disc brakes on the Pitch Sport, you'll always know you have plenty of stopping power, no matter the trail conditions. - We obsess about tires a little. OK, a lot; it's where the bike meets the trail, after all. So for the Pitch line, we chose our wide, 2.3-inch Ground Control Sport, with a versatile, fast-rolling knobby tread that offers superb grip and traction for any trail.
