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.
