![]() The latter is pretty rudimentary, and when you up the compression damping the fork chokes. The fork is coil-sprung with air assist (which can be topped up with a regular shock pump) and has external rebound and compression adjustment. Marzocchi’s fork production may have moved to Taiwan but the 66RCV retains Marzocchi’s ultra-smooth action. The high pressure makes the Demo 7 feel more lively, and the extra compression damping stopped the shock from bottoming as easily improving chassis stability. To compensate, we tried various Boost Valve pressures, finally settling on 200psi. A downspecced DHX 4 rear shock lacks the volume adjuster so you lose the ability to change the end stroke ramp up. ![]() This, combined with the reduced braking influence of the 4-bar suspension design, allows the Demo 7 to steamroll the harshest of braking bumps. To improve the Demo 7’s ability to absorb square-edge hits, Specialized has tweaked the configuration of the suspension to give a slightly more rearward axle path. It also causes the sub-stay to protrude quite a lot and as a result you rub your heel on it until you get used to it - hence the Neoprene cover. This helps to balance spoke tension on both sides of the wheel. To improve wheel strength, the entire swingarm is offset towards the drive side, then the rear wheel is re-dished to bring it in line with the front triangle. Specialized has bucked the trend for 150mm spacing rear hubs, and stuck with a 135mm rear end to save weight and keep the back end narrow for better clearance. Two shock shuttles supplied with the Demo 7 allow you to choose between a low or high bottom bracket setting, with associated 65/66deg head angles. Apart for the 1.5in head tube, reduced travel and slightly different geometry, the Demo 7 and 8 are very similar, and both frames share several component parts.
