No material has earned its keep on the downhill circuit like our M5 aluminium. 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 was constructed from it. Not only that, but 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 gives the utmost in responsive handling at speed.

For suspension, this Demo features 200mm up front via a RockShox BoXXer RC 650b 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 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.
