Adjusting the quick release mechanism |

|
|
| ||
The wheel hub is clamped in place by the force of the quick release cam pushing against | Fabric Screw |
| ||||
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 |
|
| Fabric Screw | |||
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 | Fig. 8 Fender Installation | Metal Tab Hole | ||||
implies, they serve as a |
|
|
| |||
not adjusted correctly, the secondary retention devices can reduce the risk of the | Brake | Cross Tube Hole |
| |||
wheel disengaging from the fork. Removing or disabling the secondary retention | Mounting |
|
| |||
devices may also void the warranty. |
|
|
| Plate Hole |
|
|
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, |
|
| Fender | |||
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 | Fabric |
|
| |||

|
| ||||
is the FULLY OPEN position. |
|
|
| Hole |
|
|
b. Insert the wheel between the fork blades so that the axle seats firmly at the top of |
|
| Fender Hole |
| ||
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 |
| Tension |
|
| ||
shown in Fig. 11, tighten the tension adjusting nut with your left hand until it is finger |
| FULLY | ||||
tight against the fork dropout. |

| CLOSED |
d. While pushing the wheel firmly to the top of the slots in the fork dropouts, and at the | Nut |
|
| |||
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 |
| (rotate to |
|
| ||
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 | adjust |
|

of your hand. |

The hand brake may be used to help slow or stop the stroller. |
|
|
|
|
| |
The hand brake is not a parking brake. (See section 8) |
|
|
|
|
| |
After installing the front wheel, the brake caliper will need to be placed in the closed |
|
|
|
| ||
position. Close the brake quick release lever (Fig. 10) by squeezing the brake pads |
|
|
|
| ||
against the wheel with one hand, then rotate the brake quick release lever in the counter |
|
|
| |||
clockwise direction with your other hand until |
| it |
|
|
| |
points downward. |

|
|
|
|
For the hand brake to work correctly, it is | Tension | Blade | Quick |

|
| ||
the brake lever and verify that the brake | Nut | Release |
|
