Think of it this way: when the frames telling your hands one thing & your feet another, your brain gets confused with the imbalance & the bike feels unstable. In order to fix this, we had to get to work on dialing-in the materials, shapes, & the layout. We started by creating our own mountain-specific stiffness test, & 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 & X-Large frames needed more front-end stiffness while the Smalls & Mediums were just fine. We were able to create a frame design that was 20% more efficient. & 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 & rear-end are connected at three points, & the sidearm helps keep all these points super stiff & 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 & rear shock. Suspension performance is highly dependent on frame, wheel, & rider size, so we use our Rx Tune to get each bike to land in the middle of the adjustment spectrum, & 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, youll get perfectly linear suspension. Steps were also taken to make this bike easy to live with. Threaded bottom brackets make a triumphant return, & we made room for up to a 3.0 tire. 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, & with more volume. & 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 & it drops your bottom bracket 6mm & 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 & 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 & itll come out the other end. No more lazy loop, hidden stashes of magnets, pokey spokes, or pillows to cry in. For the build, you get a solid components package with a full SRAM GX1 Eagle drivetrain, SRAM Guide R disc brakes, Rock Shox Pike RC fork & a Deluxe RT3 rear shock (130/120mm of travel respectively), & Roval Traverse Carbon 29 wheels. The Stumpjumper STs asymmetrical, FACT 11m carbon fiber construction is lightweight, stiff, & ready for technical climbs & rowdy descents. Its built off of our 29 Trail Geometry, so its both capable & comfortable. & with SWAT™ integration in the down tube, a threaded BB, easy cable routing, & a brand new chain silencer, its ready for anything the trail, or you, throw at it. With three different compression adjustments—open/pedal/lock—incredible damping performance, & our Rx Trail Tune, the Rock Shox Deluxe RT3 perfectly complements the Stumpjumper. Rock Shoxs Pike is known for its trail performance, & the RC found here has stiff stanchions, a Charger damper, & plenty of sensitivity.
