In one word: Versatility. Inspired by the great outdoors and a love for mountain biking, these dedicated trail riders want a balanced bike that performs well on everything from steep climbs to flowy singletrack to technical descents. After 30 years, their bike of choice is still the Stumpjumper FSR. Since riding styles are as diverse as the trails they ride, the bike must be lightweight, durable, and stable for efficient climbing and high-speed descending.
WHAT:
The most successful high-performance suspension system, continually refined since 1993.
WHY:
Delivers unsurpassed comfort, control, and efficiency, for more energy effort on climbs, more traction on the descent and greater pedalling 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:
Fork/hub interface featuring Specialized OS (oversized) end caps. OS 28 end caps are compatible with Roval wheels and Specialized or RockShox forks; modified version OS 24 caps available for Fox forks
WHY:
Increases front-end stiffness, which gives riders more control and confidence while riding technical terrain or pedalling out of the saddle.
HOW:
A standard hub and fork interface is not much bigger than the QR axle, which doesn’t provide a lot of surface area to support this critical junction. Our OS 28mm end caps increase that surface area by 32% to dramatically increase stiffness, while still utilizing a super-light QR axle.
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.
WHAT:
All-new carbon frames with our most advanced construction method, used on all carbon Stumpjumpers. S-Works 26″ and 29″ now feature full-carbon rear ends.
WHY:
Makes our Stumpjumpers the lightest and stiffest in their class, without sacrificing strength.
HOW:
Divides front triangle into two monocoques—with carbon fibres running continuously from tube to tube—for more precise optimization of tube shapes, sizes, and joints.
WHAT:
All-new alloy frames with customized tube manufacturing applied to all M5 alloy Stumpjumpers.
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:
Externally tuneable, trail-sensing rear shock—pioneered by Specialized and manufactured by Fox.
WHY:
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 levels.
