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:
“Brute force crushes many plants. Yet the plants rise again. The Pyramids will not last a moment compared with the daisy. And before Buddha or Jesus spoke the nightingale sang, and long after the words of Jesus and Buddha are gone into oblivion the nightingale still will sing. Because it is neither preaching nor commanding nor urging. It is just singing. And in the beginning was not a Word, but a chirrup.”
—D.H. (David Herbert)
“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)
