MAINTENANCE
Regularly check the bearings of the bicycle. Make sure to lubricate the bearings annually or
when they do not pass the below tests:
HEAD TUBE BEARINGS
The fork must turn smoothly and freely at all times. When the front wheel is off the ground, you
should be unable to move the fork up, down, or side-to-side in the head tube.
CRANK BEARINGS
The crank must turn smoothly and freely at all times and the front sprockets must not be loose
on the crank. You should be unable to move the pedal end of the crank from side-to-side.
WHEEL BEARINGS
Raise every end of the bicycle off the ground and gradually spin the raised wheel by hand. The
bearings are properly adjusted if:
The wheel can spin easily and freely.
When you put the weight of the spoke reflector toward the front or rear of the bicycle it causes
the wheel to spin back and forth multiple times.
When you push the wheel rim to the side with light force, there is no side-to-side movement.

Recommended torque for clean & dry threads:
Correct tightness of screws and bolts is essential
Using the supplied torque wrench,
screw/bolt every fastener as listed below
to the recommended torque, per the table below.
Ensure sufficient tightness by performing functional test
(see assembly instruction of parts in assembly manual).
Measure the width of the threads
(diagram below) to determine
screw or bolt size.
