SPECIALIZED S-WORKS STUMPJUMPER 15 BIKE

The Stumpjumper 15 with GENIE gives me the advantages of a bike with generous travel, and also those of a bike with reduced travel, tutto together. - Allan Cooke.

The Stumpjumper 15 eliminates any compromise in the trail mondo. Swallow big obstacles like a bike with generous travel? Done. Control, playfulness and efficiency like an XC bike? Done. Wide possibility of customization 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-level travel sensation.

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

CUSTOMIZATION: Six geometry settings, mullet setup or 29er wheels, adjustable compression curve, and more.

GENIE—the flying carpet: The greatest innovation on the Stumpjumper 15 is GENIE. This pending-patent air spring technology we invented grants the three wishes of every rider: the feeling and control of a coil spring, better bottom-out resistance than a standard air spring, and an adjustable platform for a playful feel.

THE ‘GENIO’: GENIE combines the linear stiffness of a coil spring that improves control through the "shock zone" with the progressive curve of the 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 suspensions.

WHICH IMPACT?: With 16.3% better impact force management than a traditional air-spring shock, GENIE makes the Stumpy 15 perform like a bike with greater travel. For example, the Stumpjumper 15 (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 test show that Stumpjumper 15 with GENIE provides 57% better traction than a standard air-spring shock because GENIE technology offers supple, coil-like performance that keeps the wheel in contact with the ground for a higher percentage of the tempo compared to a typical air spring.

GOODBYE BOTTOM OUT: 39% fewer bottom-out events than a standard air spring. In caso of big hits, you will 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 cornering control. The low bottom bracket, slack head angle, and optimized fork offset promote stability even on technical terrain.

A MODO TUO: the Stumpjumper 15 perfectly integrates geometry adjustment, making it the most customizable trail bike 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 clearance.

WHEEL CHOICE: With our aftermarket link you can choose large wheels both 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.

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