A spoke wrench or spoke key is a small wrench or tool used to adjust the tension in the spokes of a bicycle wheel, sulky wheel, wheelchair wheel, or similar wheel. A spoke wrench is sometimes called a nipple wrench, as it is the spoke nipple - not the spoke - that is turned in the process of changing the tension of a spoke.
Famous quotes containing the words spoke and/or wrench:
“A Stranger came to the door at eve,
And he spoke the bridegroom fair.
He bore a green-white stick in his hand,
And, for all burden, care.”
—Robert Frost (1874–1963)
“I believe we are still so innocent. The species are still so innocent that a person who is apt to be murdered believes that the murderer, just before he puts the final wrench on his throat, will have enough compassion to give him one sweet cup of water.”
—Maya Angelou (b. 1928)
