The Stumpjumper 15 is here to eliminate every compromise in the trail game. It devours bumps like a big bike, combines short-travel agility with killer playfulness and efficiency, and offers more personalisation than ever before. This bike is all about making the ride perfect for the only rider who really matters: you. BREAKTHROUGH CAPABILITY: GENIE Shock Technology brings together the best of both worlds, offering the pop and playfulness of a coil spring with the plush bottomless feel of a downhill bike. ULTIMATE CONTROL: With measurably better traction than the “Bike of the Year” Stumpjumper EVO, the Stumpjumper 15 provides unparalleled control and stability, no matter what the trail throws at you. UNMATCHED PERSONALISATION: Custom-tailor your ride with six-way geometry adjustments, your choice of mixed wheels or full 29” setup, and a tunable spring curve. The Stumpjumper 15 adapts to your riding style and terrain like never before. GENIE—THE MAGIC CARPET RIDE: The GENIE is the game-changing technology at the heart of the Stumpjumper 15. This patent-pending air spring system combines the best traits of a coil spring and air spring, giving you a plush, controlled ride with extra tunability. It’s everything a trail rider could wish for. ILLUMINATING GENIE: GENIE combines a linear spring rate through the "bump zone" for enhanced control, with a progressive rate at the end of the stroke to prevent bottom-outs. It’s the perfect blend of coil-like feel and air spring efficiency—designed to make your ride smoother and more capable than ever. WHAT BUMP?: GENIE manages bump forces 16.3% better than a traditional air shock, giving the Stumpjumper 15 the performance feel of a bike with more travel. For example, the Stumpjumper 15 (145mm rear travel) absorbs a 1080 N bump with just 101mm of travel, matching the performance of our Enduro bike (170mm travel). TRACTION GALORE: Extensive testing shows that the Stumpjumper 15 with GENIE provides 57% better traction than a standard air shock. The supple, coil-like feel keeps the wheel in contact with the ground longer, improving grip and control through technical sections. BYE-BYE, BOTTOM-OUTS: Thanks to its two-stage rising rate, GENIE delivers 39% fewer bottom-outs than a standard air spring. During big hits, the rising rate in the last 30% of the shock’s stroke cushions the impact, reducing both frequency and severity of bottom-outs. HONED GEOMETRY: The Stumpjumper 15 features geometry that blends big bike stability with a nimble feel in tight sections and efficient climbing performance. The low bottom bracket, slack head tube angle, and optimised fork offset keep you stable through rough terrain, while a spacious cockpit puts you in the sweet spot for maximum traction and cornering control. RIDE YOUR WAY: Stumpjumper 15 is the most customisable trail bike on the market. With six distinct geometry settings, you can fine-tune the bike’s performance for any style or terrain.
