Lubrication Table What When Brake Levers every six months Put one drop of oil on the pivot point of each brake lever. Caliper Brakes every six months Put one drop of oil on the pivot point of each caliper brake. Brake Cables every six months Put four drops of oil into both ends of each cable.
Inspection of the Bearings Maintenance Frequently check the bearings of the bicycle. Lubricate the bearings according to the lubrication chart or any time they do not pass the following tests: Head Tube Bearings The fork should turn freely and smoothly at all times. With the front wheel off the ground, you should not be able to move the fork up, down, or side-to-side in the head tube.
Tires Maintenance: • Frequently check the tire infl ation pressure because all tires lose air slowly over time. For extended storage, keep the weight of the bicycle off the tires. • Do not use unregulated air hoses to infl ate the inner tubes. An unregulated hose can suddenly over infl...
