4-5 Selecting air pressure, adjustment with “SAG”.
Of course, an NRS™ bike can also be ridden with “SAG”. Some riders prefer this softer, more
comfortable setting of the rear suspension system. Especially in not-competitive events, during technical
sections and in very rough terrain.
The air pressure you run in the shock varies depending on weight and riding style.
The valve on the shock is for air pressure. Adjusting air pressure determines the spring rate or stiffness of
the shock. The more air you put in, the firmer your shock will get.
By using an air pump, you may change the air pressure in the air chamber.
Goal: find the air pressure that allows you to use the maximum travel available. Ideally you want the
shock to occasionally bottom out.
“SAG” is the amount of shock travel that is used as the rider sits stationary on the bike and allows the
bicycle to perform as it was designed to. Typically, SAG is 25 - 30 % of all available travel.
To properly set the SAG, you will need measuring tape and/or calliper.
Step 1. Prepare the bicycle. Set the saddle to the correct height for your riding style.
Attach all accessories, bags, water bottles, etc. that you would normally ride with.
Step 2. Prepare yourself. Dress as you would for a normal ride, including helmet, cycling bag, etc.
Step 3. Slide the rubber O-ring (F) of the shock piston against the stop (E).
See figure 3.
Step 4. Remove the cap from the valve and push the small pin (core) inside the valve to depressurise
the rear shock’s air chamber.
Step 5. Push on the saddle as hard as you can, so the full travel of the rear suspension is used.
After the rear suspension has completely returned to its “rest” position (pull the saddle upwards
and hold the rear end of the frame, or just inflate the air chamber to approx.
150 psi.), measure the distance “L” between the stop (E) and the rubber O-ring (F).
This should be approx. 35 mm.
Step 6. Check the table of section 4-4: “Selecting air pressure, zero-SAG adjustment”, to find the
correct air pressure, depending on your weight (just as an indication).
Step 7. Adjust the pressure in the air chamber until the correct pressure has been reached
(see section 4-6: “Air pressure setting”).
