The Stumpjumper ST Comp Carbon 27.5 with 12-speed SRAM NX Eagle brings you transcendent handling, custom-tuned suspension, and an elimination of proprietary headaches—all while keeping the snappiness you look for with 27.5 wheels. With its "ST" distinction, this Stumpjumper gets slightly steeper angles and less suspension (130mm front/130mm rear).
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.
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.
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.
We revamped the SWAT™ box and added a Flip Chip that lets you to dial-in your Stumpy to your riding style. 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. 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..
