Do not worry, S-Works does not get any 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 have 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 feeling all comes down to stiffness. Thinking of it this way: when the frame is telling your hands one thing and 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 making our own mountain-specific stiffness tests, and then we went to 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 those 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 the middle of the adjustment spectrum, and this gives you the greatest possible range to fine-tune your ride. Rx Tune for each platform. So, no matter what size you prefer, you'll get perfectly linear suspension.
Steps were taken to make this bike easy to live with. Threaded bottom brackets make a triumphant return, and we made room for 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 going on with a flip chip that lets you dial into 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 So it's time to get back to you, like a newly designed ribbed chainstay protector that makes chain slap a thing of the past and almost silences the drivetrain. Lastly, we could not make 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.
