For many, an explanation for using our M5 Aluminium construction in Downhill isn't needed but here's the primary pro's: stiffness, light overall weight and strength. This is the reason you'll notice our Demo 8 I alloy has been designed with it.

Using our M5 alloy construction, the Demo 8 I Alloy works in partnership with our S3 Geometry, an asymmetric frame design and a 1.5 forged head tube resulting in this outstanding race machine. The design is fairly compact in order to increase rider input and responsiveness, while the 200mm of travel at the rear makes this bike capable of taking on the biggest hits head-on. To make a significant impact on race day, we've equipped the Demo 8 I Alloy with an ISCG 05 mount for chain guides and a rear derailleur protector to keep you shifting smoothly over the varied and unpredictable terrain.

With a RockShox BoXXer RC 650B fork, the Demo 8 I Alloy has been designed for the most demanding terrain you'll encounter. With 200mm of travel, Motion Control IS damping for ultimate efficiency, and Power Bulge reinforced lower legs that allow oversized bushings for amazing stiffness - designed for your confidence.

SRAM Guide R brakes provide strong, exact and customisable braking. They've been based upon a four-piston calliper design that supplies smooth, reliable stopping power, meanwhile the Reach Adjust feature allows you to customize the position for easy, one-finger lever pulls. And with SRAM's SwingLink technology, the cam system minimizes deadband without sacrificing modulation.

  • 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 650b 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.
  • SRAM Guide R brakes provide powerful, precise, and highly adjustable braking. Their based on a four-piston caliper design that puts out smooth, dependable stopping power, while the Reach Adjust feature allows you to customize the position for easy, one-finger lever pulls. And with SRAM's SwingLink technology, the cam system minimizes deadband without sacrificing modulation.
