No need to fret—we haven’t forgotten about all you alloy fans out there. In fact the new Stumpjumper Comp Alloy 27.5 may be the most radically designed alloy bike ever made. For real though. And with new tube shapes an asymmetrical design and the nimble 27.5 handling that we all love its plenty capable and ready to take on the trail.

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 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 and shapes.

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 sizes—we developed a specific Rx Tune for each platform. So no matter what wheel size you prefer you’ll 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 tire. Youre also free to run whatever aftermarket rear shock you want since were using standard metric shocks. 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.

The build here is no-nonsense with a focus on dependable high-performing parts like a Shimano SLX drivetrain with RaceFace cranks Shimano SLX disc brakes FOX front and rear suspension and Roval Traverse 27.5 alloy wheels.


    • The completely redesigned alloy Stumpjumper frame features an M5 alloy front- and rear-end an asymmetrical design and our 27.5 Trail Geometry so its just the right amount of both capable and comfortable.
    • 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.
    • A FOX 34 Rhythm fork handles suspension duties up front with stiff stanchions and plenty of adjustability.
