QUICK-START 2001 SID RACE/RACE ADJUST/XC/XC ADJUST IMPORTANT: THE FOLLOWING TIPS ARE TO BE USED IN CONJUNCTION WITH THE OWNER’S MANUAL AS THEY CONTAIN ADDITIONAL INFORMATION. CAUTIONS AND WARNINGS APPLY FROM THE OWNER’S MANUAL. This guide will help you quickly find your preferred settings. Remember, what might be your perfect setup may not be the same for someone else with the same bike and equal weight – we, like our bikes, are individuals!
DUAL AIR SET-UP
Some bike manufacturers give guideline air pressure recommendations in their owner's manual that should be followed, but most don’t so proceed as below... 1.
The positive chamber air pressure controls the sag of the shock. Sag is the compression of the rear wheel caused by the rider's weight. Correct sag allows the rear wheel to follow the contour of the terrain as you ride. To determine the correct sag settings you must first establish the maximum stroke of your shock. If the body o-ring is missing you need to put a small zip tie around the body (part that goes in and out during use).
2.
Remove the valve caps and release the air from the positive and negative air chambers. Gently sit on the bike and fully compress the shock, being careful that no part of the bike contacts the shock, especially protruding seatposts! Now attach the pump to the positive air valve and pump up to 50 psi. Measure between the can wiper seal and the o-ring/zip-tie, this is the stroke of the shock. The stroke will be 31, 38 or 50 mm. (Fig. 1 and 2)
3.
As all bikes are different, continue to pump up the positive chamber to a pressure (psi) rating equal to double the rider's weight. Now push the body o-ring/zip-tie against the can wiper seal. Sit on the bike in your normal riding gear and riding position with your elbow against a wall for balance.

Some people damage their pumps by screwing them in too far. As soon as the gauge registers pressure, screw ½ turn more and pump to the desired level. Use the black button on the pump to reduce air pressure. Note: That hiss you hear when you unscrew the pump is the air from the pump, not the shock. Likewise, when you attach the pump, the opposite happens and air from the shock fills the pump, reducing the pressure. All perfectly normal and no need to change your desired pressure! 4.
When you get off the bike the shock will extend and you can measure the distance between the can wiper seal and the o-ring/zip-tie, this is the sag and as a percentage of maximum stroke should be 10-20 percent for XC (firm) and 20-30 percent for Enduro (plush). Reduce the positive air pressure to increase sag and increase the positive air pressure to reduce sag. (Fig. 3)
5.
With the positive pressure set, inflate the negative chamber to match your riding style. Adjusting your shock's negative air pressure will change the initial travel characteristics (first 10-20 percent of available travel). More negative air pressure will make the shock more active over small bumps. Less negative air pressure will reduce bobbing. For enduro-style riding, with soft initial movement, use a pressure 90-110 percent of the positive pressure. For XC/Race, where harder initial travel is required, use 80-50 percent of positive pressure. (Fig. 4)

DAMPING ADJUSTMENTS
2001 SID RACE/RACE ADJUST/XC/XC ADJ
(Only for Race and XC Adjust models, which have a red rebound adjuster) Rebound is the speed at which the shock returns after being compressed. Gently turn the rebound adjuster clockwise until it stops. This is the slowest rebound setting. Now turn the adjuster counterclockwise one and a half turns. From this point you can finetune your shock. If you feel the shock is too fast in rebound, turn the adjuster clockwise, if it’s too slow – counterclockwise. Make small, ¼ turn adjustments and try again. (Fig. 5) Once you find your perfect air pressures and damping settings, make a note of them for future use.

SUSPENSION BALANCE
It is also important to balance your front and rear suspension so that they compress and return evenly. To test this, push down on the bike's top tube, at a point around 100 mm forward of the bottom bracket axle. If the bike doesn’t go down or return evenly it may be necessary to adjust the front fork to match the correctly adjusted rear. (Fig. 6)

FINE TUNING The rest is experience on the trail. Go to your favorite trail and ride various obstacles to experience how your fork works - don't forget your pump! Only change one thing at a time and then determine if this is good or bad. Each time you change a setting make a note of the change. Setting up suspension takes time. Experiment a little and enjoy!
QUICK MAINTENANCE Keep your SID rear shock clean. Treat it like you would treat yourself after a long hard ride! Clean and dry the exterior avoiding direct water pressure on the body/seal junction. Before and after every ride, put some drops of Teflon-based lube on the body seal. Push the shock up and down before wiping off the excess oil, this will keep the seal soft and help it do an even better job of keeping the dirt out. (Fig. 7) Remove, clean and grease the shock mounting hardware (pivots) after every 20 hours of riding. If the mounting hardware becomes tight it may cause premature wear to your shock.
