No need to fret—we haven’t forgotten about all you alloy fans out there. In fact, the new Stumpjumper Comp Alloy 29 with 12-speed SRAM NX Eagle may be the most radically designed alloy bike ever made. 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 material and shapes.
