ADJUST CALIPER
Check every month to ensure the caliper is centred in the rotor. If not, re-adjust it in order to centre it.
WARNING: If your braking power decreases by more than 50% then you need new calipers and new rotors.
WHEELS
Check tires, rims and spokes frequently to ensure that wheels are not damaged. Spray spokes with anti-rust spray to avoid rust, especially on the
fittings. Avoid spraying any lubricant on the disc rotor caliper and brake pads, since this will damage the brakes.
TUBES
Check your tubes for any leaks. If your tire is flat, there is most likely a hole in the tube. Patch the leak with a patch kit. If problem persists, change the
tube. Never ride a bike with a flat tire.
TIRES
Check your tires for threads and cracks every 6 months. If there are any threads or cracks the tire should be replaced. Always make sure to buy the
right tire with the appropriate width for you bicycle.
RIM
Check your rims every 6 months for dents and cracks. Replace rims if dented or cracked.

SPOKES/BELT
Periodically, carefully inspect your belt and sprockets for signs of de- terioration wear and tear. Using a worn sprocket and belt can result in property
damage and serious bodily injury, including death.
You should check your spokes regularly. If a spoke is bent or broken, it must be changed immediately since it can damage your driving ability and the
wheel/hub. Changing the spoke involves truing the wheel, which should be done by a bike mechanic.
To avoid injury to yourself and others, always make sure that your tubes, tires, rims and spokes are in order and not damaged, bent or broken.
REAR HUB
Check the freewheel every 6 months. If the freewheel does not spin freely or if it makes a strange noise, it should be checked by a bike mechanic.
