Who says you can't buy speed? Or romp up ugly, technical sections? Or rip the descents like you're water flowing without a care? Getting there is easy with the proven performance of Specialized's S-Works Stumpjumper FSR Carbon 29 Frame, the centerpiece to building the ultimate trail bike for smoking your buddies up and down. This carbon dream rig features 130mm of Brain-controlled, Fox Float, FSR travel in the rear to deliver the supreme combo of climbing efficiency and hard-charging downhill confidence. This S-Works frame is outfitted with a carbon PressFit 30 bottom bracket, a tapered headset, a 142x12mm thru-axle, and an internally-routed Specialized dropper post.
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.
