Mountain Bike Suspension Parts & Maintenance : Mountain Bike Front Suspension Tips


Most commonly seen type of suspension that
you have on bikes is front suspension and front suspension only. That really serves
to absorb a lot of the impacts that would be going to the handlebar or throwing you
off, throwing you off base. Most bikes above like $1200 these days, are full suspension
bikes, but I’m just going to talk to you right now about sort of the differences between
coil sprung suspension. So you know, a coil spring, I think, when we think of springs,
this is pretty much what we think of. It’s a coil, it compresses, it’s got, and they
come in various weights. And you know air sprung suspension fork. This suspension fork
here is air sprung. They make the same model with the same lowers and uppers and everything
else with the coil spring. And the reason that I chose an air spring over a coil spring
here, is one because it is significantly lighter. Obviously a metal coil weighs more than air,
and also because I like the adjustability of it. This particular fork, I can turn a
knob, to change the length of the fork and the amount of travel that it has. You see
that adjuster down there, as I turn this, I just moved from 140 millimeters of travel
to 125 millimeters of travel in no time at all. So moving it back up to 140 mill and
in this application, the shorter travel application, I call it shorter travel because in the realm
of things today, a fork that has five inches of travel is short compared to all the six,
seven, and eight inch travel forks out there. But for forks like this, you’ve got air pressure
on the top and then usually you have some sort of way of adjusting air pressure on the
bottom with another valve down there, which is similar to the one on top. What you do,
is you have these two chambers and you balance out the pressure between the two chambers
to get the type of ride that you want. This fork here, is about as light weight and simple
as they come. Its got air in the top, air in the bottom, air in the top, its like 2.5,
2.8 pounds.
