BOB OMS05A Front Wheel Secondary Retention Devices, Removing a Quick Release Front Wheel

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. 7). 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. 8 & 9).

c.Holding the quick release cam lever in the OPEN position with your right hand as shown in Fig. 8, 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. 7 & 9). 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.Move the wheel’s quick-release lever from the locked or FULLY CLOSED position to the FULLY OPEN position (Fig. 7). Your front fork has integral secondary retention devices. Loosen the tension adjusting nut enough to allow removing the wheel.

b.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.

6. SWIVEL LOCKOUT:

The Revolution Stroller can be used in one of two modes. The stroller can be used as a swiveling wheel stroller (Walk Mode) when the Lockout Knob is in the unlocked position (Fig. 10). Or, it can be used as a fixed wheel stroller (Jog Mode) when the swivel Lockout Knob is in the locked position (Fig. 11). To change from Walk Mode to Jog Mode, lift and slide the Lockout Knob (Fig. 10) up and all the way to the right. Then release the knob, and it will snap down. Next, rotate the fork until the pin engages and locks the fork in position. You are now ready to use the stroller in Jog Mode. To change the stroller back to Walk Mode, lift the Lockout Knob and rotate it to the left.

WARNING: Never jog with the stroller in Walk Mode because doing so could result in loss of control.

7. TRACKING ADJUSTMENT:

It should be noted that all fixed three wheeled vehicles can be easily influenced to deviate from a straight path. In some cases strollers can have or develop a tendency to pull to the right/left due to many different factors including uneven tire pressure, improper wheel installation, road conditions and manufacturing tolerances. If you find your BOB stroller to significantly track or pull to the left or right while in Jog Mode during use on flat terrain, follow the sequence of instructions below.
