SAG SET UP FOR NINER FULL SUSPENSION MODELS
Sag set up is critical to correct rear suspension function. Niner
recommends between 20-30% sag on all models. As travel
increases into the more extreme style frames, more sag can
be used (in other words, 30% on the WFO 9 is a good amount of
sag). Niner recommends starting with 25% sag on each model.
The chart below will give you measurements for each Niner full
suspension model and is a great starting point to rear suspension
setup. Niner recommends consulting your local bicycle dealer for
help in understanding suspension setup. While sag is an important
measurement to insure your suspension is setup correctly, there
are many more adjustments that can be made to your suspension
components to insure that your’re getting the most out of
your suspension. Please consult the owner’s manuals of those
suspension components for a full understanding of the different
adjustments that can be made.
To adjust sag with an air sprung shock, it will require the use of a
specific ‘shock pump’. Please insure that you have purchased the
correct pump from your local bike shop. On the rear shock, there
is a rubber o-ring that will be pushed on the stancion by the shock
body. This o-ring will indicate how much sag you have in your rear
suspension. Insure that the o-ring is pushed all the way up against
the shock body, mount your bike with your full riding gear on (to
mimic riding weight) and without bouncing get off your bike. The
distance the o-ring traveled from the shock body is the amount of
‘sag’ you have on your system. Consult the graph below for proper
measurements of correct sag per model. With your shock pump,
either increase or decrease pressure in the air spring to reach
the desired sag amount.
