1b. Inspect the Rim Wear
WARNING!
If any section of the wheel rim wear grove is no longer visible, the wheel rim should
be replaced immediately. Do not attempt to ride the bike until the rim is replaced as the braking
performance could be affected.
Each wheel features a wear grove machined into the side of the rim. If the wear grove is no
longer visible, the wheel rim is worn and should be replaced immediately.
1c. Inspect the Wheel Bearings
Over the life of the bike, the wheel bearings may become loose and/or worn and will therefore need
servicing.
To check the condition of the wheel bearing, grab the tyre of either the front or rear wheel while holding
the bike securely. Vigorously move the tyre from side to side. If the wheel moves at the wheel hub (the
centre of the wheel), the bearings may be worn.
Repairing bearings requires specialist tools. It is recommended that all bearings are repaired by
qualified bike repair technicians. Contact your local retailer for more information on bearing repairs.

It is essential that you regularly inspect and maintain your wheels, especially if your bike becomes
unstable or vibrates while riding.
1a. Inspect the Trueness of the Wheels
Over the life of the bike, the wheels may begin to run out of true, i.e. they may become buckled. This is
when the wheel rim moves from side to side.
To check the trueness of a wheel, lift the bike up and spin the wheel. If the wheel wobbles, it is out of
true and will need repairing.
Repairing wheels requires specialist tools. It is recommended that all wheels are trued by qualified bike
repair technicians. Contact your local retailer for more information on wheel repairs.
