The
Steerer Tube:
Most steerer tubes are of the Ahead variety,
which means that they have no thread.
Aluminium is the popular material as it saves
weight, while steel ones are used to keep the
prices down. Threaded steerers are only
available in steel, and most manufacturers
only offer this option on low - end forks.
2 The Stanchions:
The stanchions (Upper Legs) contain all
the internals of the fork, including the
spring medium and damping method. Chromed
steel is the smoothest and most durable
material for stanchions, but treated Aluminium
offers considerable weight saving with
negligible loss of performance.
3 The V Brake Bosses:
Most forks have protruding bosses for
attaching V - style brakes. But more and more
forks are coming on to the market with - out
them. It's all to do with the massive upsurge
in the disc brake markets.
4
Sliders:
These slide up and down the stanchions,
creating the suspension action that allows the
front wheel to track over the terrain. Sliders
are connected by a bridge ; this stops the
fork legs twisting, or moving independently.
5 Seals:
The seals do the job of keep in the oil and
air, and also keep out the trail dirt.
6 Crown:
Usually forged from Aluminium, the crown
connects the steerer tube to the stanchions.
Bonding the crown to the stanchions is lighter
than using pinch bolts, the downside of which
is that if you damage a stanchion you need to
replace the entire upper assembly.
7 Preload Adjuster:
These instantly transform the suspension fork
into a rigid one by locking out Suspension.
The bike manufacturer Cannondale even offer an
electronic version with a handlebar switch
called E.L.O. (Electronic Lock Out)
8
Disc Brake Mounts:
Most forks come with two studs on the back of
the left hand stanchion for attaching disc
brakes. The studs are normally international
standard but some manufacturers, such as
Manitou, use the Hayes post mounts, which can
limit the type of brakes that can be fitted.
9 Dropouts:
The front wheel is secured to the fork via the
dropouts, these come in standard quick -
release form, 20mm bolt - through, or a
combination of both. |
