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 our 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 our Öhlins TTX rear shock.
It's also been built off of our 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 our 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.
- The frame features a full FACT 11m carbon fiber construction for low weight and heightened levels of strength and stiffness, which is amplified by its asymmetrical frame design that still leaves plenty of access. This has also been paired with our proven S3 Geometry that increases maneuverability and responsiveness, while the 200mm of travel at the rear makes the bike capable of taking on the biggest of hits in stride.
- RockShox BoXXer Team 27.5 fork is nothing short of legendary. With 200mm of travel, a Charger Damper for maximum efficiency, and Power Buldge reinforced lower legs that allow oversized bushings for incredible stiffness, it's easy to see why it's such a fan favorite for gravity fiends.
- A SRAM X01 DH 7-speed rear derailleur makes sure that your chain stays put on the cassette, and keeps all of your power taking you forward, no matter how gnarly the terrain.
