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:
“I well recall my horror when I heard for the first time, of a journalist who had laid in a pair of what were then called bicycle pants and taken to golf; it was as if I had encountered a studhorse with his hair done up in frizzes, and pink bowknots peeking out of them. It seemed, in some vague way, ignominious, and even a bit indelicate.”
—H.L. (Henry Lewis)
“Girls who put out are tramps. Girls who don’t are ladies. This is, however, a rather archaic usage of the word. Should one of you boys happen upon a girl who doesn’t put out, do not jump to the conclusion that you have found a lady. What you have probably found is a lesbian.”
—Fran Lebowitz (b. 1951)
