The impressively low weight and amazing suspension action of Specialized's S-Works Stumpjumper FSR makes it, quite possibly, the ultimate trail bike. This carbon dream rig features Specialized's Brain-controlled FSR suspension with a Fox shock and a revolutionary Future Shock fork up front to provide 140mm of travel for the supreme combo of climbing efficiency and downhilling confidence. The flyweight Roval wheels spin up to speed fast and are impeccably stiff for awesome, pinpoint cornering. And, the S-Works is outfitted with a 2x10 XX/X0 drivetrain for flawless shifting, while the mega-powerful Avid XX discs dole out the best in braking. Just about the only thing this Stumpy won't do for you is pedal!
Specialized's FSR suspension offers plush travel, incredible control, unbeatable traction and an overall awesome ride because it's completely unaffected by pedaling and braking forces. This design also eliminates "bobbing" for optimum climbing and acceleration. You'll be amazed.
The Brain is the mastermind behind Specialized's ultra-efficient suspension designs. It automatically turns the suspension "on" and "off" almost instantaneously to always provide the perfect ride. It consists of an inertia valve mounted inside a near-vertical cylinder near the rear axle. The inertia valve controls the shock's ability to compress; the resulting system responds to terrain input (bumps and dips), but not to rider input (pedaling). Forces from the ground activate the inertia valve inside the Brain, which opens and allows the shock to absorb bumps. All Brains also feature Brain Fade technology, which by using the blue dial on top of the Brain cylinder, you can control the breakaway threshold of the inertia valve in your Brain from ultra rigid and efficient to super plush and active and anywhere in between. So you can set up your bike to climb and sprint like a hardtail and still absorb bumps for maximum control over rough terrain; the ideal combination for parlaying all your hard efforts into off-road speed.
Specialized's FACT (Functional Advanced Composite Technology) carbon frames and components are made from the finest materials and utilize a unique manufacturing process that creates amazing durability, awesome efficiency and super-low weight.
This frame’s head tube is 1 1/2 inches in diameter at the bottom and 1 1/8 inches at the top. This maximizes front-end stiffness for awesome steering precision and control, while allowing the use of standard 1 1/8-inch stems and not adding much weight.
