To make the Stumpjumper 15 the ultimate trail bike, the Specialized Ride Dynamics team focused on making the best trail moments better and eradicating the bummers. This approach led to some seriously technical breakthroughs that raise the bar when it comes to capability, control, and enabling the rider to easily personalize their Stumpjumper 15 to perfectly suit their style and the terrain they’re riding. The biggest single innovation on the Stumpjumper 15 is GENIE. This game-changing air spring technology grants every trail rider’s three wishes: feel and control of a coil spring, better bottom-out prevention than a standard air spring, and a tunable “platform” for a playful feel

Changing the Game of Trail Bike Suspension Forever
The Specialized Ride Dynamics team holistically developed suspension that measurably increases the bike’s ability to calmly handle big terrain while retaining the platform and poppy feel of a shorter travel bike when you want it. In fact, the bike is incredibly supple on small to mid-size bumps, devours square-edged hits, feels bottomless on big drops, provides a solid platform when you want it, and is plenty responsive to pedal inputs. Sounds too good to be true, but really, it does. In fact, testing shows that the Stumpjumper 15 with GENIE delivers a 57% reduction in traction loss time and 39% fewer severe bottom out events compared to a standard air spring. 

Capability and Control.
This bike’s geometry delivers big bike capability when you need it, a nimble feel in tight sections, and lively, efficient climbing manners. The generous cockpit centers you on the bike, optimising traction and corner control. The low bottom bracket, slack head tube angle, and optimized fork offset keep things stable in the rough while allowing you to choose between destroying the turn, floating through it, or nailing the inside line. Three rear-center dimensions across the size range optimize handling for riders of different sizes. 

Select the Size that Suits Your Style (Not Your Inseam)
S-Sizing is based on what matters: rider style, not inseam. Six sizes, all with similar head tube lengths and standover, allow you to choose the size that best suits how you ride. Smaller S-Size numbers will be more nimble, thanks to their shorter reach and front-center measurement, while bigger S-Sizes deliver more stability and a roomier ride.

Occasionally, without notice, manufacturers change product design and/or specifications.
