Bicycle Usage
A timing chain, also called a sync chain, is used on tandem bicycles, to synchronize crank movement between the captain (front rider) and stoker (rear rider). As with auto engines, proper tension of the timing chain is necessary to prevent premature wear of the drivetrain components. Tension is adjusted by means of an eccentric bottom bracket.

Famous quotes containing the words bicycle and/or usage:
“Consider a man riding a bicycle. Whoever he is, we can say three things about him. We know he got on the bicycle and started to move. We know that at some point he will stop and get off. Most important of all, we know that if at any point between the beginning and the end of his journey he stops moving and does not get off the bicycle he will fall off it. That is a metaphor for the journey through life of any living thing, and I think of any society of living things.”
—William Golding (b. 1911)
“...Often the accurate answer to a usage question begins, “It depends.” And what it depends on most often is where you are, who you are, who your listeners or readers are, and what your purpose in speaking or writing is.”
—Kenneth G. Wilson (b. 1923)
