a quick release.
.
Each time, before you use the stroller, check that the wheel is securely clamped.
The wheel quick release uses a cam action to clamp the stroller wheel in place (Fig.
9). Because of its adjustable nature, it is critical that you understand how it works, how
to use it properly, and how much force you need to apply to secure the wheel.
WARNING: The full force of the cam action is needed to clamp the wheel securely.
Holding the nut with one hand and turning the lever like a wing nut with the other
hand until everything is as tight as you can get it will not clamp the wheel safely
in the dropouts.
Adjusting the quick release mechanism
The wheel hub is clamped in place by the force of the quick release cam pushing against
one dropout and pulling the tension adjusting nut, by way of the skewer, against the
other dropout. The amount of clamping force is controlled by the tension adjusting nut.
Turning the tension adjusting nut clockwise while keeping the cam lever from rotating
increases clamping force; turning it counterclockwise while keeping the cam lever from
rotating reduces clamping force. Less than half a turn of the tension adjusting nut can
make the difference between safe clamping force and unsafe clamping force.
Front Wheel Secondary Retention Devices
All 2007 and newer BOB Strollers have front forks which utilize secondary wheel retention
devices designed to help keep the wheel from disengaging if the quick release is
incorrectly adjusted. Secondary retention devices are not a substitute for correct quick
release adjustment. The secondary retention devices on your stroller are the integral
type that is formed into the outer faces of the front fork dropouts.
WARNING: Do not remove or disable secondary retention devices. As its name
implies, they serve as a back-up for a critical adjustment. If the quick release is
not adjusted correctly, the secondary retention devices can reduce the risk of the
wheel disengaging from the fork. Removing or disabling the secondary retention
devices may also void the warranty.
Secondary retention devices are not a substitute for correct quick release
adjustment. Failure to properly adjust the quick release mechanism can cause
the wheel to wobble or disengage, which could cause you to lose control and fall,
resulting in serious injury or death.
Installing a Quick Release Front Wheel:
a. Move the quick release cam lever so that it curves away from the wheel (Fig. 9). This
is the FULLY OPEN position.
b. Insert the wheel between the fork blades so that the axle seats firmly at the top of
the slots that are at the tips of the fork blades the fork dropouts. The quick release
cam lever should be on the left side of the stroller (Fig. 11 & 12).
c. Holding the quick release cam lever in the OPEN position with your right hand as
shown in Fig. 11, tighten the tension adjusting nut with your left hand until it is finger
tight against the fork dropout.
d. While pushing the wheel firmly to the top of the slots in the fork dropouts, and at the
same time centering the wheel rim in the fork, move the quick release cam lever
upwards and swing it into the FULLY CLOSED position (Fig. 9 & 12). The lever should
now be parallel to the fork blade and curved toward the wheel. To apply enough
clamping force, you should have to wrap your fingers around the fork blade for
leverage, and the quick release cam lever should leave a clear imprint in the palm
of your hand.
WARNING: Securely clamping the wheel takes considerable force. If you can fully
close the quick release without wrapping your fingers around the fork blade for
leverage, and the quick release cam lever does not leave a clear imprint in the
palm of your hand, the tension is insufficient. Open the lever; turn the tension
adjusting nut clockwise a quarter turn; then try again.
e. If the quick release cam lever cannot be pushed all the way to the fully closed position
parallel to the fork blade, return the lever to the OPEN position. Then turn the tension
adjusting nut counterclockwise one-quarter turn and try tightening the lever again.
Removing a Quick Release Front Wheel:
a. To remove the front wheel, open the brake quick release (Fig. 10).
b. Move the wheels quick-release lever from the locked or FULLY CLOSED position
to the FULLY OPEN position (Fig. 9). Your front fork has integral secondary retention
devices. Loosen the tension adjusting nut enough to allow removing the wheel.
c. Raise the front wheel a few inches off the ground and tap the top of the wheel with
the palm of your hand to knock the wheel out of the front fork.
7. HAND BRAKE:
The hand brake may be used to help slow or stop the stroller.
