Tech Tip: Bleeding air out your forks.
by Geoff Den
I often see riders, who have obviously heard that they need to
let the air out of their forks from time to time.
Having seen loads of guys, who have good intentions, but the actually
don’t know exactly what to do, and they then let the air out
their forks, while the bike with the wheel on the ground. Often
with the rider on it or else standing on its own or on the side
stand. This in fact lets more air out as the forks are somewhat
compressed, and the result is the fork then actually has a small
vacuum inside, holding the fork back from extending fully. This
reduces the air volume in the fork, making less of an air cushion,
and makes the forks stiffer.
The correct way to do this, is to have the bikes front wheel off
the ground, and then to bleed the air from the forks. Preferably
every time just before you ride. If you do MX, do it before every
Moto, as air builds up during a ride, so if you bleed before your
first Moto, it will more than likely have air inside the fork after
the Moto. Bleed them each time just before you ride. A set of Fork
Bleeders, which you just compress whilst the bike is on the stand(wheel
off the ground), are inexpensive, and work like a charm. It takes
literally 2 seconds to bleed the air out the forks using them.
