The Stumpjumper 15 Alloy was designed with the goal of making no compromises. Devour jumps like a big bike? Easy. Efficiency, playful character, and control with just the right amount of travel? It ticks the boxes. Many customization possibilities to make it the ultimate Trail MTB in your eyes? You've got them.

REVOLUTIONARY CAPABILITIES: GENIE shock technology gives the bike a dynamic playful character, but also the feeling of riding a long-travel DH mountain bike.

ULTIMATE CONTROL: Extra traction compared to the Stumpjumper EVO, already named the benchmark Trail bike by many international media outlets.

UNRIVALLED CUSTOMIZATION: Six geometry customization options, mullet or 29-inch wheel configuration, damping curve management, and more.

GENIE — The feeling of riding on a magic carpet: The biggest innovation of the Stumpjumper 15 Alloy is GENIE. This patent-pending air spring technology that we invented grants all three wishes of any Trail Rider: the feel and control of a coil spring, better bottom-out prevention than a standard air spring, and an adjustable "platform" for a playful package.

GENIE IS INSPIRING: GENIE combines the linearity of a coil spring, improving control in rough sections, with the progressivity of an air spring at the end of the stroke to avoid untimely bottom-outs. Truly, it's the best of both worlds – coil and air – with complementary adjustment possibilities. Say goodbye to compromises and hello to the future of damping. AN IMPACT? WHAT IMPACT? : With impact force management that's 16.3% more efficient than a traditional air shock, GENIE allows the Stumpy 15 to be ridden like a longer-travel MTB. For example, the Stumpjumper 15 Alloy (with 145mm rear wheel travel) and our Enduro (170mm travel) both use 101mm of travel to absorb a 1,080 N shock force. TRACTION GALORE: Extensive field tests prove that the Stumpjumper 15 Alloy with GENIE offers 57% more traction than a standard air shock, because GENIE technology gives you smooth, coil-like performance and keeps the wheel in contact with the ground for a longer period.

BYE, BYE, BOTTOM-OUTS: 39% fewer bottom-outs than a standard air spring. During large impacts, you benefit from an increasing ratio in the last 30% of the GENIE shock's travel. Thanks to this two-stage ratio, GENIE reduces the frequency and intensity of bottom-outs.

OPTIMIZED GEOMETRY: The geometry of this MTB offers great capabilities when you need them, an agile feel in winding sections, and lively and efficient climbing capabilities. The wide handlebar centers you on the bike, optimizing traction and control in corners.

RIDE YOUR WAY: The Stumpjumper 15 Alloy features benchmark geometry adjustment, making it the most customizable Trail bike ever designed. Six distinct geometry settings allow you to fine-tune performance for any style and any terrain.

WHEEL CHOICE: With our optionally available shock links, you can choose between 29-inch wheels front and rear or mix things up with a 27.5-inch rear wheel for a more playful and fun ride.

TAKE EVERYTHING WITH YOU: The Stumpjumper 15 Alloy's SWAT 4.0 allows you to store your essentials inside the downtube, an innovation we pioneered.
