Beeline: The classic full suspension bike, made for the first mountain bikers back in the day, now designed with a balanced 150mm travel front 140mm travel rear, with an M5 alloy frame, with each frame size independently designed and produced to optimise stiffness to weight.
The Stumpjumper range for 2019 offers a broad spectrum of models, with 3 categories of Stumpjumper, available in 27.5 and 29 inch wheel sizes (with different amount of travel for the different wheel sizes):
Stumpjumper:
-
Fast & Planted Bike
-
27.5: 150mm Travel Front & Rear
-
29: 150mm Travel Front, 140mm Rear
Stumpjumper ST:
-
Snappy & Nimble Handling
-
27.5: 130mm Travel Front & Rear
-
29: 130mm Travel Front, 120mm Travel Rear
Stumpjumper Evo:
-
Gravity Focused Ride
-
27.5 150mm Travel Front & Rear
-
29: 150mm Travel Front, 140mm Rear
This Stumpjumper 29 uses an M5 Alloy frame, equipped with a Fox Float Rhythm 34 Fork and a Fox Float DPS Performance Shock with 3 position compression adjust, delivering consistent suspension movement across the travel. The suspension system offers great absorption impact, pedalling efficiency and active suspension under braking.
With the Stumpjumper comes great attention to detail, with internal cable routing on a Full Suspension bike that works and is easy to use. The chainstay protector offers silence as does the chainguide.
Sram’s NX Eagle drivetrain is a 1x12 set up, with a massive 11-50 cassette and a 32T chainring, with Roval Traverse 29 wheels for a great, fast rolling wheelset with a Specialized Butcher Front Tyre and a Purgatory Rear Tyre, both 2.6 wide.
Specialized: 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.
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.
