The Stumpjumper 15 with GENIE gives me the benefits of a bike with generous travel, and also those of a bike with short travel, all at once. -Allan Cooke.

The Stumpjumper 15 erases any compromise in the world of trail riding. Eat up big obstacles like a bike with generous travel? Done. Control, playfulness and efficiency like an XC bike? Done. Wide customization possibilities to make it perfect for the only biker that really matters: you? Done, done, done.

REVOLUTIONARY CAPABILITY: GENIE technology combines a snappy, playful ride with a DH touring feel.

SUPREME CONTROL: Tangibly better traction than the “Bike of the Year,” the Stumpjumper EVO.

GENIE—The Flying Carpet: The biggest innovation on the Stumpjumper 15 is GENIE. This patent-pending air spring technology we invented fulfills every rider's three wishes: the feel and control of a coil spring, better bottom-out prevention than a standard air spring, and an adjustable platform for feel playful.

THE 'GENIE': GENIE combines the linear stiffness of the coil spring that improves control through the "bump zone" with the progressive curve of the air spring at the end of the stroke to avoid bottoming out. Truly, it's the best of both worlds – coil and air – with extra adjustability. Say goodbye to compromises and say hello to the future of suspension.

WHICH SHOCK?: With 16.3% better shock force management than a traditional air spring shock, GENIE makes the Stumpy 15 perform like a bike with more travel. For example, the Stumpjumper 15 (with 145mm rear wheel travel) and our Enduro (170mm travel) both use 101mm of travel to absorb a shock force of 1080N.

GOGO TRACTION: Extensive field testing shows that the Stumpjumper 15 with GENIE provides 57% better traction than a standard air spring shock because GENIE technology offers flexible performance, similar to that of a coil spring, that holds the wheel in contact with the ground for a greater percentage of the time than a typical air spring.

GOODBYE BOTTOM OUT: 39% fewer bottom out events compared to a standard air spring. In the case of large bumps, you will benefit from the progressive curve in the last 30% of the GENIE stroke. Thanks to its two-phase behavior, GENIE reduces the frequency and severity of bottom out events.

PERFECTED GEOMETRY: This bike's geometry offers great ability when you need it, agility in tight sections, and efficiency on climbs. The large cockpit centers you on the bike, optimizing traction and control when cornering. The low bottom bracket, relaxed head angle and optimized fork offset promote stability even on technical terrain.

YOUR WAY: The Stumpjumper 15 seamlessly integrates geometry adjustment, making it the most customizable trailbike ever. Six distinct geometry settings let you fine-tune performance for any style and terrain. The head angle and bottom bracket height can be precisely adjusted to ensure stability or light.

WHEEL CHOICE: With our aftermarket links you can choose between large wheels on both the front and rear, or you can use a 27.5" rear wheel for a more responsive and playful ride. Whatever you choose, the geometry doesn't come influenced.

CARRY EVERYTHING YOU NEED: The SWAT 4.0 compartment on the Stumpjumper 15 increases downtube storage, an innovation we pioneered.
