A is for air

• Inflate tires to rated pressure as listed on the sidewall of the tire.
• Use a pressure gauge to insure proper pressure.
• Check for damage to tire tread and sidewall; replace if damaged.

B is for brakes

• Inspect pads for wear; replace if there is less than 1/4th of pad left.
• Check pad adjustment; make sure they do not rub tire or dive into spokes.
• Check brake level travel; at least 1” between bar and lever when applied.

C is for cranks, chain and cassette

• Make sure that crank bolts are tight; lube the treads only, nothing else.
• Check the chain for wear; 12 links should measure no more than 12 1/8 inches.
• If the chain skips on the cassette, it may need an adjustment or a new one.

Quick is for quick releases

• Hubs need to be tight in the frame; the quick release should engage at 90 degrees.
• The hub quick release should point back to insure that nothing catches on it.
• Inspect brake quick releases to make sure they reengage.

Check is for check it over

• Take a quick ride to check if derailleurs and brakes are working properly.
• Inspect the bike for loose or broken parts; tighten, replace or fix them.
• Pay extra attention to the bike to keep it in good working condition.
