2019 Specialized Stumpjumper Comp Carbon 27.5 12 FS Mountain Bike Blue

Our design goal for the new stumpjumper was simplebuild 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 frames 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 sizeswe developed a specific rx tune for each platform. So no matter what wheel size you prefer youll 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 tyre. Youre also free to run whatever aftermarket rear shock you want since were 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 couldnt 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 itll 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 27.5 wheels. The stumpjumpers asymmetrical, FACT 11m carbon fiber construction is lightweight, stiff, and ready to take on the trail. Its built
off our 27.5 trail geometry, so its 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, its 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. Srams 12-speed nx eagle groupset features a wide gear range that delivers climbing and descending efficiency in spades.
