  • Manipulated M5 alloy FSR frame with Mag Link has 8″ of rear wheel travel; an oversized, forged head tube; rear derailleur protector, with suspension linkage engineered for the world’s toughest terrain
  • Cane Creek Double Barrel coil shock provides a downhiller’s dream of externally adjustable high-and-low-speed rebound and compression settings for maximum control over challenging terrain

  • New Roval DH rims are 30mm wide, laced with DT Swiss spokes to Specialized hubs with a 20mm front thru-axle and 150x12mm rear thru-axle hub creates a reliable, and super strong wheelset that easily handles the biggest hits
  • Specialized Butcher DH 26 x 2.3″ soft dual compound front and rear tyres offer great traction with Monster Team approved tread, and a bombproof casing
  • SRAM X0 DH crankset with carbon arms, 36T chainring and Gamut bashguard is built with speed and durability in mind
  • Renthal Fat Bar is 780mm wide for maximum control for riding the steepest descents, just like the Monster boys
  • Custom Avid Code X0 hydraulic disc brakes for lightweight precision, modulation and power, plus carbon levers with tool-less reach

For pros like Sam Hill, Brendan Fairclough, or any aspiring DH racer, the mountain is at its best when it pushes the boundaries of technical terrain. These fate-tempting riders rip down the toughest terrain on earth in the most aggressive way imaginable, so they want quite simply the most badass DH bike around: bomb-proof, uber-fast, technologically cutting-edge, and of course sexy!

M5 alloy frame with 12 x 150mm rear end, fewer sharp edges/corners, and a sleeker finish than previous frame designs.

Minimizes mud and debris build-up to keep weight low and allow rider to navigate steep, technical terrain unfettered.

Responding to input from Sam, Brendan, and the Monster Energy mechanics over the years, we keep the corners soft to avoid collecting debris and the frame sleek to limit any narrow spaces that might collect mud.

The strongest and lightest components available, expressly designed for the DH experience.

Makes the Demo as strong and light as possible, without sacrificing compatibility with industry-standard interfaces (so aftermarket components will still fit). Helps riders maximize attainable speeds, while considerably reducing risk.

Working closely with the Monster Energy team and various manufacturers allows us to dial the spec to work in perfect concert with the Demo platform. We test the components at every stage of development and make adjustments to elicit customized performance from crucial components, like wheels, brakes, and cranksets.

Our proprietary FSR suspension, specially tuned for the rigors of DH racing with sub-seatstay.

Keeps the Demo super-svelte by making the rear end compact and sleek, while lowering the centre of gravity. This gives the bike razor-sharp handling without sacrificing our legendary FSR suspension performance.

The sub-seatstay allows us to drive the shock off the chainstays, as opposed to the seatstay, which effectively lowers the centre of gravity.
