Abstract
A split tube containing a lubricant is engaging a bicycle chain. The lubricator tube is carried by the chain during the initial chain operation until the tube end contacts a barrier surface on the chain drive mechanism. The barrier may be the pivoting idler arm, the derailer mechanism, or a portion of the bicycle frame. The device brings the lubricant in intimate contact with the chain allowing the use of semi-solid, liquid, and solid-solvent mixture of lubricants.
