Mountain Bike Suspension Parts & Maintenance : Mountain Bike Rear Sag Setting Tips


Just like with your front suspension, setting
sag with your rear suspension is incredibly important. In fact, some suspension designs
are designed to operate only within a certain sag window. So, here with my rear air shock
it’s fairly easy to set the sag. There’s an O-ring that’s on the shaft that I can just
push up–as you can see it’s right there. I’ll push it all the way up, cycle the bike
a couple times just to make sure I break through any static friction that may have been there
from sitting around, and now I’m going to lean on my bike stand, assume my riding position,
probably get up like this instead, I’ll get off, and let’s see how much sag I got. So
that is
a little bit less than twenty millimeters of sag out of a total of sixty millimeters
of stroke, so that’s about in the range of what we’re looking for. Most suspension designs
you can alter your sag height depending on how you want the bike to handle and feel.
Obviously the softer you run your suspension and the more sag that you have, the more willowy
the bike is going to be, but it’s also going to be softer on those little ripples through
the trail and stuff like that. If you’re a larger rider and you hit things harder, you
probably might want to run a little bit less sag to compensate for that. You can also,
if you want your bike to be a little bit slacker or a little bit higher, you can run more or
less sag to compensate for that.
