The latest Specialized Stumpjumper impresses with increased travel, a proprietary shock, and innovative design tweaks
Genie shock offer impressive grip and small bump sensitivity
Well-rounded, easy to get along with geometry (that’s also widely adjustable)
Large in-frame storage compartment
Not an exceptional value
No derailleur cable routing
Wireless shifting only

Specialized EVO'd the Stumpy 15, making it a lot more interesting as a Shore-worthy trail bike.
Beautiful paint job (dark cherry to black fade, gloss, lightly sparkled)
Comfortable S-Works Power Pro with Mirror saddle
Flawless Fox Transfer NEO Factory dropper post
Sleek Roval Traverse SL II rims with I9 Hydra 2 hubs
Easy tubeless setup
Updated Butcher and Eliminator tires perform well
Adjustable geometry with included headset cups
Genie shock offers tunability and unique characteristics
High price ($14,499 CAD / $11,299 USD)
Fox 36 fork feels flexy for heavier riders (195 lbs / 88 kg)
Rear tire casing (Grid Trail) feels thin and may need more support in wet conditions
XTR brakes not as powerful as SRAM Maven, contamination issue encountered
Handlebar width is 800mm across all sizes, not size-appropriate
No internal shift cable routing on carbon models
Bike setup may need adjustment (too much air in shock, head angle may need slackening)

The Stumpjumper 15 brings new GENIE shock technology to the venerable trail bike, which sees more travel and further refinements.
Incredible suspension performance thanks to GENIE shock tech
Excellent fit and geometry
Build kit is on point and delivers excellent value
Refined frame design and features
Stock wheels on the Comp build are under-gunned for the Stumpy’s capabilities
Nov 2024 · Dario DiGiulio
The alloy Stumpy packs a punch for the price, and you can run a cable-actuated derailleur.
Suspension is impressively sensitive
Extensive adjustment to alter geometry, wheel size, and shock performance
Can descend like a bigger bike
Quite heavy for a trail bike, due primarily to frame weight
Genie shock warrants extended setup testing
Can be hard to balance sensitivity and support
