About this bike
Relentless, fast, aggressive—no matter how you describe it, downhill racing is demanding. Starting with the bike, you're inserting control into a borderline uncontrollable situation wherever you can. But when it comes to harnessing gravity's pull, while also maintaining confident handling, it simply doesn't get any better than the S-Work Demo 8. It's constructed from Specialized's finest carbon fiber, FACT 11m, for unparalleled stiffness and strength. At the front, you'll find 200mm of travel coming through a custom-tuned RockShox BoXXer Team 27.5 fork, and at the rear, you get 200mm of travel via their Ohlins TTX rear shock. It's been built off of their S3 27.5 geometry, ensuring a roomy top tube for added control, ultra-short, nimble chainstays, a low bottom bracket that keeps you feeling planted, and a slack front end that provides the utmost in responsive handling at speed. The build is also dialed-in, sparing absolutely no expense in providing the utmost in lightweight, durable performance. This means that you get powerful SRAM Code RSC brakes and 200/180mm Centerline rotors, a precise one-by X01 DH seven-speed drivetrain, strong & stiff Roval 27.5 wheels, and Specialized's legendary Butcher & Slaughter DH tires for the ultimate in traction and control. Add it all up, and you get everything you need to send-it down the mountain with more speed than you ever thought possible.
