Whether you ride on the road or the track a well-lubricated drive chain will not only prolong the life of expensive-to-replace components, it will also help the engine to deliver its power to the rear wheel. Poorly lubricated chains will overheat, causing them to stretch and increasing friction on the sprockets, which will wear down more quickly, all of which affects the chain’s ability to drive the rear wheel. Worse still, the O-rings in modern chains are liable to perish if insufficiently protected by chain lube.
