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 26 and 29- inch wheel sizes, and is also offered in riding-style-specific EVO models. The SJ FSR is fully loaded with advanced features, like AUTOSAG to simplify suspension setup, the Dangler chain retention system to keep the ride quiet, and the internally routed Command Post IR dropper seatpost, so you’re always in the ideal riding position—climbing or descending.
WHAT The most successful high-performance suspension system continually refined since 1993.
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 26” and 29” EVO models with more gravity-oriented geo 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 26” and 135mm on the 29”. The spec includes wider handlebars, bigger tires, a Command Post, and more robust wheels.
BRAIN SHOCK W/ AUTOSAG
WHAT Externally tunable, highly pedaling efficient trail-sensing rear shock with AUTOSAG—pioneered by Specialized and manufactured by FOX.
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 used on all carbon Stumpjumpers. S-Works 26” and 29” feature full-carbon rear ends, Evo is M5 rear.
WHY Makes our Stumpjumpers the lightest and best riding in their 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.
WHAT Alloy frames with customized tube manufacturing applied to all M5 alloy Stumpjumpers. Featuring PF30 BB, tapered headtube, and 142+ rear end.
WHY Creates a stronger, lighter bike with clean lines.
HOW High-pressure fluid is forced through each tube to eliminate welds and achieve more precise tube shaping.
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 in 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.
