The Best Trail Bike of the Year, Officially
Stumpjumper 15 has been named “Best in Test” by Enduro Magazine, standing out among the most advanced trail bikes of the year. With its GENIE suspension, balanced handling, and all-terrain versatility, it truly is One Bike to Rule All Trails.
GENIE Grants Every Trail Rider’s Wishes
This game-changing, patent-pending air spring technology that we invented grants every trail rider 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.

What’s Inside GENIE?
Check out how GENIE combines the control-enhancing linear spring rate of a coil spring through the “bump zone” with the progressive spring rate of an air spring at the end of the stroke to reduce bottom-outs. It's the best of both worlds – coil and air – with extra tuneability. Say goodbye to compromises and hello to the future of riding.

Eats Bumps Like an Enduro
GENIE shock technology gives the Stumpy 15 16.3% better bump performance than ‘Bike of the Year’ Stumpjumper EVO. It literally uses more travel for the same size bump, thanks to its flatter spring curve in the first 70% of travel.
57% Better Traction
GENIE delivers 57% less traction loss time than a standard air-sprung shock because GENIE technology gives you supple, coil-like performance, which keeps the wheel in contact with the ground a greater percent of the time than a typical air spring would.
Bye, Bye, Bottom Outs
Send it with confidence knowing that in field testing GENIE eliminated 39% of severe bottom out events compared to a standard FOX Float air spring.
