freeride A style of riding that is defined by short course technical acrobatics and athletes that defy gravity. Generally, the bikes and components required for freeriding are stronger and heavier than their lightweight cross-country brethren. Combine the aerial pyrotechnics of freeriding with some longer trails and courses, as is typical of cross-country riding, and now you're looking at all-mountain riding., all-mountain A style of bicycle riding that melds the stamina and conditioning required of cross-country with the technical abilities of freeriding., cross-country A style of bicycle riding that is defined by long rides, lightweight bicycles and stamina. |
Install the shock with the spring retainer, but without the spring. (To remove the spring, read Changing Springs.)
Carefully cycle the suspension through its entire travel.
Check that all parts of the shock are clear of the frame and swingarm as it cycles through the travel.
Properly place the spring back onto the shock.
Some things to consider:
If you ride in extreme conditions, service your shock more frequently. Check the maintenance schedule for your shock.
Wash your shock with soap and water only.
Do not use a high pressure washer to clean your shock.
Extensive internal service should be performed by FOX Racing Shox or an Authorized Service Center.
Check that quick-release levers properly adjusted and tightened.
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.
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 Racing Shox for further inspection and repair.
Check headset adjustment. Adjust headset if loose, according to manufacturer’s recommendations.
Check that brake cables or hoses are properly fastened.
Check that the front and rear brakes operate properly on flat land.
Loosen the preload ring until the spring freely moves.
Lift up the spring and remove the spring retainer.
Slide the spring off the shock body. Depending on your bike model, you may need to remove the reducers to remove the spring.
Orient the new spring correctly (see Spring Orientation below) and slide it onto the shock body.
Place the spring retainer back on the shock and under the spring ensuring that the open slot on the spring retainer rests on the flat part of the spring end.
Tighten the preload ring just until the spring no longer moves.
Turn the preload ring one additional full turn.
When placing the spring back on the shock body, it is important that the spring is correctly oriented. Essentially, the space in the spring retainer should rest on the flat part of the spring, and not on the segment of the spring where it starts to coil back under itself. Rotate the spring or spring retainer until the correct orientation is achieved.
An improperly oriented spring can fail prematurely, causing loss of control of the bicycle, which can result in serious or fatal injuries. The pictures below demonstrate correct and incorrect spring orientation. Correct spring orientation applies to all FOX Racing Shox rear shocks that utilize coil springs:
You can also view a Flash video on Setting Sag.
To set sag on your VANILLA R trunion shock:
Measure sag, and compare it to the recommended sag setting shown in the Coil Spring Settings table below. Continue if the sag is not to specification.
Adjust the preload ring accordingly:
If sag is lower than on the table, turn the preload ring counterclockwise. Always ensure that the spring is secure and does not freely move.
AFTER THE PRELOAD RING ENGAGES THE SPRING, TURN THE PRELOAD RING CLOCKWISE ONE TURN. IF THE PRELOAD RING NEEDS TO TURNED COUNTERCLOCKWISE FROM THIS POINT TO ACHIEVE PROPER SAG, YOU WILL NEED TO OBTAIN A LOWER RATE SPRING.
If sag is higher than on the table, turn the preload ring clockwise no more than full two turns after the preload ring engages the spring.
IF AFTER THE PRELOAD RING ENGAGES THE SPRING, MORE THAN 2 FULL CLOCKWISE TURNS ARE REQUIRED TO ACHIEVE THE PROPER SAG SETTING, YOU WILL NEED TO OBTAIN A HIGHER RATE SPRING.
If necessary, contact FOX Racing Shox or an Authorized Service Center to obtain a higher- or lower-rated spring.
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 approximately 15 clicks of adjustment.
For slower rebound, turn the red adjuster knob clockwise.
For faster rebound, turn the red adjuster knob counterclockwise.
The ProPedal on your VANILLA R trunion shock is set at the factory, and cannot be adjusted.
