tires. To inflate a Presta valve tube using a Presta headed bicycle pump, remove

fig. 24

the valve cap; unscrew (counterclockwise) the valve stem lock nut; and push down

 

on the valve stem to free it up. Then push the pump head on to the valve head,

 

and inflate. To inflate a Presta valve with a Schraeder pump fitting, you’ll need a

 

Presta adapter (available at your bike shop) which screws on to the valve stem

 

once you’ve freed up the valve. The adapter fits into the Schraeder pump fitting.

 

Close the valve after inflation. To let air out of a Presta valve, open up the valve

 

stem lock nut and depress the valve stem.

 

H.K2 Razorback Set-Up Instructions

1.Air Pressure Spring Adjustment. To receive the best performance from your K2 Razorback, it is necessary to adjust the suspension. The Razorback is equipped with a rear air shock. Air pressure within the shock unit becomes the suspension spring, and should be set to a rider’s weight and riding style. A guideline for the airpressure can be found on the left chainstay of the Razorback (fig. 25). Find your weight on the graph, and note the recommended pounds per square inch (p.s.i.) rating. It should be noted

that air pressure is a personal preference and can be adjusted accordingly. Riding without enough air pressure can cause excessive shock “bottom out” (or compression) and

damage the frame or shock unit. There are two Schrader-type valves on the Razorback shock body. The one closest to the seattube will adjust the air spring (fig 26), while the second located closest to the red rebound adjuster is an air bleed valve. It is recommended that the bleed valve always be set to 0 p.s.i. To adjust the air spring, remove the dust cap and fit the high pressure pump to the valve. Note the current p.s.i. rating and add or reduce the amount of pressure accordingly. For more information, refer to the Fox Shox Owner’s Manual.
