The 15th generation of the Specialized Stumpjumper unifies the brand's trail lineup, merging the previous standard and EVO models into a single 145mm-travel platform. Designed to handle a broad spectrum of terrain, it pairs that rear travel with either a 150mm or 160mm fork. The frame drops the distinctive asymmetrical sidearm strut of its predecessor in favor of a cleaner, more traditional silhouette, while retaining the signature SWAT downtube storage.

The defining feature of this generation is the proprietary Fox Genie rear shock, a dual-chamber air spring developed to maximize early-stroke traction while resisting harsh impacts. Available in both carbon and aluminum frame options, the Stumpjumper 15 is positioned for riders who want a highly adaptable trail bike that can comfortably pedal all day and still manage aggressive, steep descents without requiring a full enduro setup.

03 / Geometry

Geometry & fit.

6 sizes published.

Specialized utilizes its S-Sizing system for the Stumpjumper 15, offering six frame sizes based on reach rather than seat tube length. This allows riders to size up for high-speed stability or size down for a more agile, maneuverable feel, aided by short seat tubes that accommodate long-travel dropper posts across the board. The two smallest sizes come standard with a mixed-wheel setup, while the larger sizes roll on dual 29-inch wheels, though all frames can be converted to a mullet configuration via an aftermarket linkage.

The geometry is highly adjustable, featuring a chainstay flip chip and interchangeable headset cups that yield six distinct configurations. Riders can tune the head tube angle from a steep, responsive setting down to a slack, downhill-oriented stance, while the flip chip alters bottom bracket height and chainstay length. In its neutral settings, the bike balances a steep seat tube angle with a relatively high stack height. This combination places the rider in a comfortable, upright pedaling posture that keeps weight centered over the bottom bracket for efficient climbing, while the generous reach provides a stable stance during aggressive descending.

The lineup.

6 builds, ranging $4,000 – $11,300.

The Stumpjumper 15 lineup spans a wide price range, starting with accessible aluminum models and topping out with premium S-Works carbon builds. A critical distinction between the frame materials is cable routing: the carbon frames are designed exclusively for wireless drivetrains and lack routing for mechanical shift cables, whereas the alloy frames retain traditional cable ports.

Suspension spec dictates the bike's exact travel and intent. Most builds feature a 150mm fork and the inline Fox Genie air shock. However, the EVO-designated and coil-specific builds step up to a 160mm fork paired with a piggyback or coil shock, catering to riders focused on sustained, aggressive descending.

Across the board, Specialized prioritizes heavy-duty stopping power, equipping nearly all models with four-piston SRAM Maven or TRP DH-R EVO brakes and large rotors. Drivetrains rely heavily on SRAM's electronic Transmission ecosystems on the carbon models, while the alloy builds utilize mechanical Shimano setups. Value is often highlighted in the mid-tier carbon Pro and Expert builds, which deliver high-end suspension dampers and reliable wireless shifting without the extreme premium of the S-Works tier. Lower-end alloy models offer a more approachable entry point, though their heavier overall weight and basic wheelsets are notable compromises.

05 / Reviews

From the press.

26 reviews from the cycling press.

Reviewers consistently praise the Stumpjumper 15 for its exceptional rear-wheel grip and composure on rough descents. The proprietary Genie shock is the focal point of most evaluations, delivering a highly supple initial stroke that isolates the rider from trail chatter. This translates to "incredible descending traction and control" (Singletracks) through rocky and root-heavy sections. As the shock moves deeper into its travel, the secondary air chamber closes off, creating a firm ramp-up that testers found highly effective at managing large impacts and flat landings.

While the suspension excels on the way down, climbing performance draws a slightly more nuanced response. The bike pedals efficiently on smooth ascents, but some riders experienced a "wallowing sensation" (Flow Mountain Bike) on steep, technical climbs when their weight shifted rearward. Fortunately, the shock's outer air sleeve can be tuned with volume bands to increase mid-stroke support, allowing riders to dial in a firmer, more responsive pedaling platform if desired.

The carbon models are generally celebrated for their low weight and energetic feel, making the platform a "true do-it-all bike" (Theloamwolf) for varied terrain. However, testers note that the aluminum versions are "quite heavy for a trail bike" (Pinkbike), which slightly dulls the bike's uphill acceleration but maintains its descending stability.
