WARNING!
The pressure exerted by your finger to move the lever should be very light;
you do not need to force the mechanism. In case of a problem, contact your
retailer. You can also refer to the manufacturer's notice.
4.4.3 Setting the pre-stress of the fork (SAG)
In order to fully profit from your bike's potential, the suspension should be set up for your
weight. This is a technical procedure that can be carried out by your local retailer if you do not
have the necessary knowledge or material.
This setting is commonly called «SAG», which corresponds to the compression of the
suspension under the weight of the cyclist. The level of SAG varies according to the type
of fork and the type of usage of the bike. These values can be found in the technical notice
available on the website https://www.moustachebikes.com/en/manuals// in the Services
section.
The SAG is a value expresses as a percentage, and defines the length of displacement of the
stanchions in relation to the fork or shock body, caused by your body weight when you are sat
on the bike. Let's take an example:
My fork has 140 mm of travel (which means the stanchions are 140mm long). The recommended
SAG is 25%. To convert this SAG value into millimeters you just need to use the following
formula:
Which in this example case gives us: SAG [in mm] = 25% (0.25) x 140 mm = 35 mm
So, my body weight pushes the stanchions into the legs by 35 mm.
The SAG is calibrated by setting the pre-stress of the shock or the air pressure in the pneumatic
cartridge depending on the type of fork. To set up fork SAG carry out the following steps:
For Coil spring with oil damping.
• Sit on the bike in a normal position and wearing your usual riding kit (helmet, bag and
accessories...). You can lean against a wall in order to avoid any brusque movements
on the bike.
• Step off your bike gently to avoid a harsh movement and measure the "SAG". A SAG that
is too weak indicates that the pre-stress of the spring is too high. You should therefore
turn the adjustment lever towards the «-». Inversely, a too high level of SAG indicates that
the spring's pre-stress is too weak, and you should therefore turn the adjustment lever
towards «+».
• Repeat these steps until you find the right level.
Hint: If your fork is not equipped with a rubber O-ring that you can use to see the SAG position,
you can place a plastic zip tie on the fork stanchion which will carry out the same function.
Other settings can be carried out so you profit as much as possible from your suspension
system. Refer to the dedicated notice or to your local bike retailer.
SAG [in mm] = SAG [en %] x Travel [in mm]
