At a glance

The 2018 Specialized Demo 8 I Alloy is an Downhill Carbon mountain bike. It sports 27.5" wheels, is priced at $5,000 AUD, has RockShox suspension and a SRAM drivetrain. The bike is part of Specialized's Demo range of mountain bikes.

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 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 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 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 RS brakes, a durable one-by SRAM drivetrain, and our legendary Butcher & Slaughter DH tyres, you get a bike that wants nothing more than to be pushed harder and faster.
