“In 1981 the first production mountain bike \u2013 it was called Stumpjumper \u2013 hit the scene, bringing the fun of off-road riding to people around the world.<\/strong><\/p>\n\n\n\n


Fast forward 43 years, and we\u2019re debuting the 15th full-suspension version of the Stumpjumper. Sure, there\u2019s been a lot of change and innovation over those four decades, but the goal of bringing more control, capability, and fun to trail riders remains unchanged.<\/strong> <\/p>\n\n\n\n

Our passion for riding fuels our commitment to elevating the trail experience – for ourselves, but also for all trail riders who share our obsession.<\/strong><\/p>\n\n\n\n


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\u2019re riding. The biggest single innovation on the Stumpjumper 15 is GENIE.<\/strong> <\/p>\n\n\n\n

This game-changing air spring technology grants every trail rider\u2019s three wishes: feel and control of a coil spring, better bottom-out prevention than a standard air spring, and a tunable \u201cplatform\u201d for a playful feel.”<\/strong><\/p>\n\n\n\n

Here’s our full breakdown of everything you need to know about the all-new Stumpjumper 15<\/strong>, from its new GENIE tech to its increased traction & control.<\/p>\n\n\n\n

\n

Breakthrough Capability<\/h2>\n\n\n\n

To rule all trails, Specialized have upped the bike\u2019s ability to tackle big terrain and a variety of trail conditions. <\/p>\n\n\n\n

Suspension, geometry, chassis, sizing, and spec work together to calmly dispatch chunky trails, big hits, steep descents, technical climbs, rocks, roots, drops, and tight corners.<\/p>\n<\/div>

Game-Changing Suspension<\/h2>\n\n\n\n

The Specialized Ride Dynamics<\/strong> team holistically developed suspension that increases the bike\u2019s ability to handle big terrain, whilst still retaining the platform and poppy feel of a shorter travel bike when you want it.\u00a0<\/p>\n\n\n\n

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.<\/p>\n\n\n\n

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<\/strong> and<\/strong> 39% fewer severe bottom-out events<\/strong> compared to a standard air spring. <\/p>\n<\/div><\/div>\n\n\n\n

\n

Frame of Reference<\/h2>\n\n\n\n

Specialized engineered the FACT 11M Carbon Frame<\/strong> as a single unit that hits the stiffness target they established for trail riding.<\/p>\n\n\n\n

The key goal of the Stumpjumper 15 was to use materials and design as efficiently as possible. <\/p>\n\n\n\n

The elegant, simple \u201cform follows function\u201d chassis design was data-driven. Extensive analysis showed their engineering team that \u201cspending\u201d grams to reinforce the shock link resulted in a more efficient approach to achieving stiffness than the previous \u201cSidearm\u201d design. The result is excellent handling with less mass.<\/p>\n<\/div>

What is GENIE?<\/h2>\n\n\n\n

“GENIE<\/strong> is a Specialized patent-pending technology for their Pneumatic Spring Assist (PSA)<\/strong> air spring innovation.<\/p>\n\n\n\n

By employing two separate but connected positive air chambers, the overall air volume is increased, resulting in a much flatter spring curve for the first 70% of the shock\u2019s stroke; this \u201csofter\u201d spring delivers coil-like bump force management throughout the bump zone.<\/p>\n\n\n\n

\"specialized-genie\"<\/a><\/figure>\n\n\n\n

As the shock compresses into the final 30% of the travel, the GENIE band slides over and closes the ports to the outer air chamber, effectively reducing the overall volume.<\/p>\n\n\n\n

This results in a much more progressive spring curve for the last 30% of stroke, preventing bottom-outs more effectively than a standard air spring.”<\/p>\n\n\n\n

“Riding GENIE for the first time is mind-blowing because it\u2019s unlike anything you\u2019ve experienced. For example, experienced riders expect the bike to \u201cwallow\u201d in slalom-y sections based on how plush it rides through most of the travel. <\/strong><\/p>\n\n\n\n

Surprisingly, GENIE provides a platform you can trust, thanks again to the late-stage rising rate, making for a fun, playful bike that can still plow like a bike with much more travel. <\/strong><\/p>\n\n\n\n

You\u2019ll recalibrate immediately and appreciate the \u201cbest of both worlds\u201d rideability GENIE brings to your rides. As if that wasn\u2019t cool enough, by installing or removing spacers in the air chambers, you can independently tune the middle-stroke and end-stroke spring characteristics to suit your style and the day\u2019s terrain.<\/strong><\/p>\n\n\n\n

What\u2019s crazy about GENIE is how you can change the bike\u2019s personality with different volume spacers. It opens up a tuning range nobody has ever had before.”<\/strong><\/p>\n\n\n\n
