When measuring the length of spokes, what are some common methods used to ensure accuracy and what are the potential consequences of incorrectly measuring spoke length on the overall performance and safety of a bicycle wheel. Are there any specific tools or techniques that are preferred over others, and how do different types of spokes, such as straight gauge or butted, affect the measurement process. Additionally, are there any best practices for documenting and recording spoke length measurements for future reference, and how often should these measurements be checked and updated to ensure the continued integrity of the wheel.
