Front Wheel
Check the wheel hub before attaching it to the fork by rotating the
threaded axle. It should be smooth with no lateral movement. Insert
the front wheel into the fork dropouts. Tighten the wheel nuts using
the appropriate 14mm or 15mm wrench. Spin the wheel checking for
trueness. Some bicycles have wheel axles that incorporate a Quick
Release (QR) mechanism. This allows easy wheel removal without
the need for tools. The mechanism uses a long bolt with an adjusting
nut on one end, and a lever operating a cam-action tensioner on the
other. If the wheel is fitted with a Quick Release type axle, turn the
adjusting nut so that the locking lever is moved to the closed position
with a firm action. At the halfway closed position of the quick release
lever, you should start to feel some resistance to this motion. Do not
tighten the quick release by using the quick release lever like a wing
nut. If the quick release lever is moved to the closed position with no
resistance, clamping strength is insufficient. Move the quick release
lever to the open position, tighten the quick release adjusting nut,
and return the quick release lever to the closed position.
Correct Quick Release Axle Setting
1.
To set, turn the lever to the open position so that the curved
part faces away from the bicycle.
2.
While holding the lever in one hand, tighten the adjusting nut
until it stops.
3.
Pivot the lever towards the closed position. When the lever is
halfway closed, there must be firm resistance to turn it
beyond that point. If resistance is not firm, open the lever and
tighten the adjusting nut in a clockwise direction.
4.
Continue to pivot the lever all the way to the closed position
so that the curved part of the lever faces the bicycle.
