Specialized Stumpjumper 15 Expert

In ’81, we unleashed the first Stumpjumper, flipping the switch on mountain biking worldwide. Fast forward through 43 years of blood, sweat, and dirty-toothed grins, and today we're dropping the 15th full-suspension Stumpjumper.

Stumpjumper 15 is here to obliterate every trade-off in the trail game. Devour bumps like a big bike? Check. Short-travel control, playfulness, and efficiency? Double check. How about a heaping helping of personalization to make it perfect for the only rider who really matters—you?  Check, check, check.

Breakthrough Capability
GENIE Shock Technology combines a poppy, playful ride with a bottomless DH feel

Ultimate Control
Measurably better traction than “Bike of the Year” Stumpjumper EVO

Unmatched Personalization
Six-way geometry adjust, mixed wheel or 29”, tunable spring curve, and more

The biggest single innovation on the Stumpjumper 15 is GENIE. This patent-pending air spring technology invented by the Specialized Science Club grants every trail rider three wishes: 

1. Feel and control of a coil spring
2. Better bottom-out prevention than a standard air spring
3. Tunable “platform” for a playful feel. 

According to the data, this means 16.3% better bump force management and 39% fewer severe bottom-outs compared to a standard air-sprung shock. It's the best of both worlds – coil and air – with extra tunability. Say goodbye to compromises and hello to the future of riding.

Have it your way with seamlessly integrated adjustability that makes Stumpjumper 15 the most personalizable trail bike ever. Six distinct geometry settings allow you to hone its performance for any style, any terrain. The head angle is adjustable to three settings between 63 and 65.5 degrees via a unique eccentric upper headset cup. Fine-tune the bottom bracket height up or down by 7mm by swapping the Horst link chips. Drop it down for a more stable ride, or set it high for clearance. Choose your wheel size with our aftermarket shock links.
