Hub Bearing Adjustment
When checked, the hub bearings of either wheel will require
adjustment if there is any more than slight side play.
1. Check to make sure neither locknut is loose.
2. To adjust, remove wheel from bicycle and loosen the locknut on
one side of the hub while holding the bearing cone on the same
side with a flat open end wrench.
3. Rotate the adjusting cone as needed to eliminate free play.
4. Re-tighten the locknut while holding the adjusting cone in position.
5. Re-check that the wheel can turn freely without excessive side play.
How To Fix a Flat Tire
If you need to repair a tire, follow these steps:
1. Remove the wheel from the bicycle.
2. Deflate the tire completely via the valve.
Loosen the tire bead by pushing it inward all the way around.
3. Press one side of the tire bead up over the edge of the rim.
Note: Use tire levers, not a screwdriver, otherwise you may
damage the rim.
4. Remove the tube, leaving the tire on the rim.
5. Locate the leaks and patch using a tube repair kit, carefully
following the instructions, or replace the tube.
Note: Ensure that the replacement tube size matches the size
stated on the tire sidewall and that the valve is the correct type
for your bicycle.
