Overview

About this bike

When sending it full gas down the run, you want confidence that your bike will perform as it should, and no material has earned its keep on the downhill circuit like our M5 aluminum. The reasons for this are stacking, but primarily, it can all be summed up by stiffness, light overall weight, and strength. That's why you'll find that our Demo 8 I Alloy was constructed from it in order to make your next shred-sesh that much more fun. It's more than a one-trick-pony, though, as it also features a 1.5-inch forged head tube to enhance most of these qualities. As for the ride, the Demo 8 pairs our S3 Geometry with an asymmetric frame design that ensures plenty of access, 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. For suspension, this Demo features 200mm up front via a RockShox BoXXer RC 27.5 and 200mm of travel at the rear controlled by a custom-tuned FOX VAN RC. Together, the combo ensures that you'll be able to rocket over any terrain with confidence. And when you add in a build kit consisting of SRAM's powerful Guide RS brakes, a durable one-by SRAM drivetrain, and our legendary Butcher & Slaughter DH tires, you get a bike that wants nothing more than to be pushed harder and faster. - M5 alloy construction works in tandem with our S3 Geometry, an asymmetric frame design, and a 1.5” forged head tube to create the ultimate race machine. The design is relatively compact in order increase maneuverability and responsiveness, while the 200mm of travel at the rear makes the bike capable of taking on the biggest of hits in stride. And to fill out all of the details that make the difference on race day, we’ve included an ISCG ‘05 mount for chain guides and a rear derailleur protector to keep you shifting smoothly through rock gardens and unexpected strikes. - RockShox BoXXer RC 27.5 fork is purposefully designed for the most demanding terrain on earth. With 200mm of travel, Motion Control IS damping for maximum efficiency, and Power Buldge reinforced lower legs that allow oversized bushings for incredible stiffness, it'll leave you with nothing but confidence. - The clutched SRAM GX rear derailleur all but eliminates dropped chains, so you're able to rail through rock gardens while still being able to sprint out of them.
