The M5 aluminum Stumpjumper FSR Comp EVO 29 is purpose-built for the aggressive trail rider. It separates itself from other carbon Stumpjumpers with a slacker head angle and more travel. The Comp EVO 29 features a custom Fox Float CTD Evolution shock with AUTOSAG, RockShox Revelation RC3 29 fork, custom Formula C1 hydraulic disc brakes, and 2Bliss Ready Specialized Butcher and Purgatory Control 2.3" tires.
Hot, new asymmetrical graphic on the M5 alloy frame with 135mm of rear wheel travel, EVO 29 geometry, tapered head tube, 142mm dropouts, PF30 BB, and sealed cartridge bearing pivots pushes the boundaries of trail riding
FOX Float CTD Evolution shock with ground-breaking proprietary Specialized AUTOSAG features 3 compression settings: Climb, Trail and Descend, and rebound adjust.
RockShox Revelation RC3 29 140mm fork has a tapered steerer, 15mm thru-axle, 3-position damper: open, medium, and firm, rebound adjust, and lockout for a lightweight trail bike capable of ripping technical descents
Wider Roval 29 rims mated to Specialized Hi Lo hubs, oversized endcaps, 142mm rear hub spacing, and 12mm thru-axle increase wheel stiffness for more confident riding
The 2Bliss Ready Specialized Butcher and Purgatory Control 29 2.3" tires for premium control on challenging trail conditions
Custom SRAM S-1250 10-speed All-Mountain double-ring shifts fast while the PF30 spindle makes for an efficient and stiff crankset
Custom Formula C1 brakes provide great braking power and modulation while the Specialized Butcher and Purgatory tires keep the traction while rolling fast
SRAM X9, Type2, 10-speed mid-cage rear derailleur and 11-36 cassette for smooth and reliable shifts
Specialized Command Post BlackLite uses a remote lever to adjust the saddle height on-the-fly to maximize climbing and descending performance
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.
