Our sport has come a long way since the Stumpjumper debuted in 1981, but its heart remains true to adventure and premium trail riding performance. The ultra-versatile Stumpjumper FSR is available in both 29-inch and 650b wheel sizes, and also offered in riding-style-specific EVO models. The Stumpjumper FSR is fully loaded with advanced features, like AUTOSAG to simplify suspension setup, SWAT to get you out of a trail jam, and the Command Post dropper seatpost so you’re always in the ideal riding position—climbing or descending.
WHAT The most successful high-performance suspension system continually refined over 20 years.
WHY Delivers unsurpassed comfort, control, and efficiency, for less effort on climbs, more traction on the descent and greater pedaling performance.
HOW Strategic pivot points decouple suspension from drivetrain and braking forces to eliminate bob and squat, creating a fully active, fully independent system.
WHAT 29-inch and 650b EVO models with more gravity-oriented geometry and spec, plus longer travel.
WHY To accommodate the many riders who appreciated the precise handling prowess of their Stumpjumper FSR, but were modifying them so they could shred more aggressive downhill lines.
HOW It starts with the EVO geo: a little lower BB for better cornering and a little slacker for more confidence over obstacles or riding steeper sections. This allows us to increase the travel to 150mm on the 650b and 135mm on the 29-inch. The spec includes wider handlebars, bigger tires, a Command Post, and more robust wheels.
BRAIN SHOCK WITH AUTOSAG
WHAT Externally tunable, highly pedaling efficient trail-sensing rear shock with AUTOSAG—pioneered by Specialized and manufactured by FOX (on non-EVO models).
WHY Ensures perfect sag every time and boosts efficiency and control over smooth and rough terrain.
HOW When a rider encounters bump forces, the Brain’s inertia valve disengages, allowing oil to flow and the shock to immediately transition from firm (efficient) to fully active (compliant) suspension settings. The external Brain Fade dial allows riders to fine tune their suspension feel.
FACT IS CONSTRUCTION
WHAT FACT IS carbon frames on all carbon Stumpjumpers. S-Works 29er features full carbon rear end; EVO is M5.
WHY Makes the Stumpjumper the lightest and best riding in its class, without sacrificing strength.
HOW Divides front triangle into two monocoques—with carbon fibers running continuously from tube to tube—for more precise optimization of tube shapes, sizes, and joints.
TRAVERSE FATTIE WHEELSET
WHAT All-new rims with a 30mm internal width on carbon models and 29mm on alloy (EVO models only).
WHY Wide rims provide better control and traction due to increased stability and the ability to run lower tire pressure without the risk of "rolling" a tire.
HOW Utilizing our Zero Beak Hook design and an all-new 30mm internal width rim (29mm on alloy rims), the Traverse Fattie provides a tubeless-ready, stable wheel configuration by dispersing a rider's tire contact patch over a wider area of terrain.
WHAT Revolutionary SBC technology, manufactured by FOX, automatically sets the proper sag and air pressure in your shock.
WHY Quicker and easier sag adjustment that guarantees the perfect setting for optimal suspension performance.
HOW When a rider sits on the saddle, a specially designed transfer port in the shock releases air pressure until a set level, based on the rider’s weight, which equalizes the positive and negative chambers. At this point the shock is at the perfect sag.
