We have added an enhanced feature to our jogging strollers that allows the customer to fine tune the tracking of their stroller. This document is designed to supplement to the Owner’s Manual. Proceed with initial setup and use of your stroller and only refer to this document if you believe there is a tracking problem with your stroller.
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 tire pressure, wheel installation, road conditions and manufacturing tolerances. If you find your BOB stroller to significantly track or pull to the left or right during use on flat terrain, follow the sequence of instructions below.
Tracking Adjustment Instructions:
The
release lever is on the opposite side, Fig. 3. Reinstall the front wheel, secure the wheel and brake quick release levers.
b. Perform roll test again. If the stroller still consistently pulls to the left or right when pushed straight, proceed to next step.
7)Fine tune tracking of stroller is accomplished by using the adjustment knobs shown in Fig. 4.
If your stroller pulls to the right, proceed as follows:
Rotate axle 90o

1)Confirm the rear wheels are installed correctly. Refer to step 4 of the Owner’s Manual for installation instructions.
2)Confirm the front wheel is installed correctly. Refer to step 6 of the Owner’s Manual for correct installation instructions. When tightening the quick release make sure the front wheel is pushed straight and equally toward the back of the dropouts.
3)Check the tire pressure, making sure the tire pressure is exactly the same on all three tires.
4)Roll test the stroller as described below. It is recommended you have someone assist with this task in order to catch and return the stroller.

Fig. 1 illustrates the roll test process.
a. Empty the stroller. Do not roll test with a child or any occupant in the stroller.
b. Find a location on level ground approximately 16 ft. long. It is helpful to use an existing
c. Align the stroller so the rear wheels are perpendicular to the straight line. Push and release the stroller trying carefully not to influence its direction to the left or right so it rolls straight down the test path. This step should be performed more than once to make sure the stroller was not biased left or right by the pushing action.
d. If the stroller consistently pulls to the left or right when pushed straight, proceed with the steps below until tracking is satisfactory. Fig 1. illustrates how to interpret the results.
Reference convention: Left and right are described as viewed from the
operator’s frame of reference (behind the stroller). Example: The parking brake lever is on the left side of the handlebar.
5)Rotate the front axle. Often tracking can be corrected by simply rotating the front wheel axle.
a.Open the front wheel quick release, step 6 of the Owner’s Manual. Rotate axle 90 degrees in dropout, Fig. 2 and retighten quick release.
b.Perform roll testing again. If the stroller still consistently pulls to the left or right when pushed straight, proceed to next step.
6)Reorient the front wheel. Many times the tracking can be corrected by removing the front wheel and flipping it around and reinstalling it.
a.Open the front wheel and front brake quick releases, step 6 of the Owner’s Manual. Remove the front wheel and flip it around so the quick
