This bike eliminates every trade-off in the trail game. It devours bumps like a big bike while maintaining short-travel control, playfulness, and efficiency. The FACT 11m carbon chassis and carbon link with SWAT integration provide a rigid yet responsive platform, while the head tube angle adjustment allows you to fine-tune geometry to your riding style. The suspension setup combines a 160mm FOX FLOAT 36 Factory fork with GRIP X2 damper and a 145mm FOX FLOAT X GENIE Factory rear shock, delivering both capability and control across all trail conditions. Complete Shimano XTR Di2 electronic drivetrain ensures precise, reliable shifting, while Roval Traverse SL II wheels with Industry 9 Hydra 2 hubs provide lightweight, durable performance. All You Need To Know About Stumpjumper 15 EVO 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.
