Dual Rate Control Valve (DRCV) Technology

The Dual Rate Control Valve (DRCV) deploys a dual air chamber system, in which a secondary air chamber opens at a specific point during shock travel. The DRCV system combines the efficiency of a smaller air volume ride with the plush response of a large air volume shock deeper into its travel stroke.

The secondary air chamber is positioned on the top of the shock, requiring the upper eyelet to be placed midway between the secondary chamber and main air sleeve.

Installing Your Shock

If you are installing your shock (on a bike for which the shock is original equipment only):

  1. Install the shock.
  2. Remove the dual-chamber valve air cap and depress the core pin fully to let all the air out of the main and secondary air chambers. Be sure to read the caution note about the dual-chamber air valve in Setting Sag.
  3. Carefully cycle the suspension through its entire travel.
  4. Check that all parts of the shock are clear of the frame and swingarm as it cycles through the travel.
  5. Pressurize your shock to a minimum of 50 psi and no more than 300 psi. You will tune to a more specific air pressure in the Setting Sag section below.
  6. Set sag.

General Maintenance

There may be a small amount of air sleeve lubricant residue on the body. This is normal. If this residual air sleeve lubricant is not present, this is an indication that the air sleeve should be re-lubricated. Some other things to consider for all shock models:

Before You Ride

  1. Clean the outside of your shock with soap and water and wipe dry with a soft dry rag. Do not use a high pressure washer on your shock.
  2. Inspect entire exterior of shock for damage. The shock should not be used if any of the exterior parts appear to be damaged. Please contact your local dealer or FOX for further inspection and repair.
  3. Check that quick-release levers (or thru-axle pinch bolts) are properly adjusted and tightened.
  4. Check headset adjustment. If loose, adjust according to manufacturer’s recommendations.
  5. Check that brake cables or hoses are properly fastened.
  6. Check that the front and rear brakes operate properly on flat land.

Setting Sag

To set sag:

  1. Be sure that you cycle your DRCV shock past 60% of its full travel at least once.
  2. Measure sag, and compare it to the recommended sag setting shown in the Air Spring Setting Guidelines table below. Continue if the sag is not to specification.
  3. Locate the dual-chamber air valve on the shock and remove the air valve cap.

    Note:  The dual-chamber air valve looks very similar to a Schrader valve, but internally it's quite different. This valve automatically equalizes air pressure between the main and secondary air chambers, as air is pumped into or released from this dual-chamber valve.

    CAUTION:  Do not attempt to service the dual-chamber air valve, or remove and reinstall its core! Doing so will risk causing irreparable damage to the valve, in turn impairing normal shock operation. Any damage to this valve is repairable only by an Authorized Fox Service Center.

  4. Thread the FOX Racing Shox High Pressure Pump hose onto the air valve until the pump indicates a pressure reading on the gauge. Turn an additional 1¼ turns, however do not over-tighten. As you thread the additional 1¼ turns, you'll notice a second increase in pressure on the gauge. This effect is caused by air pressure equalizing between the main and secondary air chambers.

    Note:  For proper sag adjustment, it is mandatory to thread the pump hose an additional 1¼ turns past the point where the pump initially shows a pressure reading.

  5. Add or release air pressure, until the desired pressure setting is shown on the gauge. Refer to the Air Spring Setting Guidelines table below for the proper sag setting.

    Note:  It is necessary to cycle the shock beyond 50% of its full travel at least once after the pump hose is removed, before measuring your sag.

  6. Unthread the pump from the air valve, cycle your shock and measure sag.
  7. Repeat steps 1-6, until your proper sag adjustment is achieved. Replace the dual-chamber air valve cap.

RP23 Model

Adjusting Rebound for the RP23

Rebound controls the rate at which your shock returns after it has been compressed. The proper rebound setting is a personal preference, and changes with rider weight, riding style and conditions. A rule of thumb is that rebound should be as fast as possible without kicking back and pushing the rider off the saddle.

The rebound knob has 12-15 clicks of adjustment.

For slower rebound, turn the red adjuster knob clockwise.

For faster rebound, turn the red adjuster knob counterclockwise.

ProPedal for the RP23

ProPedal Lever

The ProPedal lever allows for on-the-fly ProPedal adjustment. ProPedal damping reduces pedal-induced suspension bob. The two ProPedal lever settings are:

Use each setting to adjust the shock for different riding conditions and situations. For example, use PROPEDAL for riding to the top of the mountain, and then switch to OPEN for the descent.

To determine which ProPedal position is better for your condition and situation, pedal the bicycle and monitor the shock movement. Switch between positions and select the one that reduces suspension movement most effectively while providing the desired amount of bump absorption.

Because suspension designs and riding skills vary, optimal settings can vary from bike to bike and rider to rider. For more precise ProPedal tuning and to further eliminate pedal-induced bob while maintaining bump compliance, adjust the ProPedal knob. As with the ProPedal lever, switch positions and select a setting that reduces suspension movement most effectively while providing the desired amount of bump absorption.

ProPedal Knob

The 3-position ProPedal knob (shown below) allows you to adjust ProPedal firmness when the ProPedal lever is in the PROPEDAL position. The ProPedal knob only changes damping when the ProPedal lever is in the PROPEDALposition.

The ProPedal knob settings are denoted by the numbers etched onto the ProPedal knob. The three ProPedal knob settings are:


 

To adjust the ProPedal knob:

  1. Turn the ProPedal lever to the PROPEDAL position, as shown in graphic above.
  2. Lift the ProPedal knob (see frame #2 in the drawing below).
  3. Turn the ProPedal knob clockwise (relative to the ProPedal knob facing the user) until the selection you want—1, 2, or 3—is aligned with the ProPedal lever (#3). The ProPedal knob clicks twice per setting as it turns. The first click occurs as you exit the current setting; the second click as you engage the new setting.
  4. Push the ProPedal knob into its new position (#4).

    CAUTION:  The ProPedal knob should NOT be adjusted on-the-fly. It should only be adjusted while in a stationary position.

The ProPedal lever allows for on-the-fly ProPedal adjustment. ProPedal damping reduces pedal-induced suspension bob. The three ProPedal lever settings are:

Use each setting to adjust the shock for different riding conditions and situations. For example, use PROPEDAL 3 for riding to the top of the mountain, PROPEDAL 1 for general trail riding, then switching to OPEN for the descent.

To determine which ProPedal position is better for your condition and situation, pedal the bicycle and monitor the shock movement. Switch between positions and select the one that reduces suspension movement most effectively while providing the desired amount of bump absorption.
