SPECIALIZED STUMPJUMPER 15 ALLOY FRAME

Officially the best trail bike of the year
The Stumpjumper 15 has been named “Best in Test” by Enduro Mountainbike Magazine, standing out among the most advanced trail bikes of the year. Thanks to the GENIE suspension and its handling and versatility, the Stumpjumper 15 is truly the bike that dominates every trail.
The Stumpjumper 15 Alloy with GENIE gives me the advantages of a bike with generous travel, and also those of a bike with short travel, all together. - Allan Cooke.

The Stumpjumper 15 Alloy eliminates every compromise in the mondo of trail. Devour big obstacles like a bike with generous travel? Done. Control, playfulness and efficiency like an XC bike? Done. Wide customization options to make it perfetto for the unico rider who really matters: you? Done, done, done.

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

SUPREMO CONTROL: Tangibly better traction compared to the “Bike of the Year”, the Stumpjumper EVO.

GENIE—the flying carpet: The biggest innovation on the Stumpjumper 15 Alloy is GENIE. This patent-pending air spring technology we invented grants the three wishes of every rider: the feel and control of a coil spring, better bottom-out resistance than a standard air spring, and an adjustable platform for a playful feel. THE ‘GENIUS’: GENIE combines the linear stiffness of a coil spring that improves control through the “bump zone” with the progressive curve of an air spring at the end of the stroke to prevent bottom-outs. Really, it’s the best of the two mondi – coil and aria – with extra adjustability. Say goodbye to compromises and welcome the futuro of suspension.

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

TRAZIONE A gogo: extensive field testing shows that the Stumpjumper 15 Alloy with GENIE provides 57% better traction than a standard air-spring shock because GENIE technology offers compliant, coil-like performance that keeps the wheel in contact with the ground for a greater percentage of the tempo compared to a typical air spring.

GOODBYE BOTTOM OUT: 39% fewer bottom-out events than a standard air spring. In the case of big hits, you’ll benefit from the progressive curve in the last 30% of the GENIE stroke. Thanks to the two-fasi behavior, GENIE reduces the frequency and severity of bottom-out events.

REFINED GEOMETRY: the geometry of this bike offers great capability when needed, agility in tight sections, and efficiency on climbs. The spacious cockpit centers you on the bike, optimizing traction and control in corners. The low bottom bracket, slack head angle and optimized fork offset promote stability even on technical terrain.

YOUR MODO: the Stumpjumper 15 Alloy perfectly integrates geometry adjustment, making it the most customizable trail bike ever. Six distinct geometry settings allow you to fine-tune performance for any style and terrain. The head angle and bottom bracket height can be precisely adjusted to ensure stability or clearance.

WHEEL CHOICE: With our aftermarket link you can choose 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 is not affected.

BRING TUTTO YOU NEED: The SWAT 4.0 compartment on the Stumpjumper 15 Alloy increases the spazio in the down tube, an innovation we pioneered.
