As long as your tools are good, selecting the wrong spokes for a wheel is more likely to result from an outright mistake than from a measurement error. Though you should always measure carefully, wheel measurement is more forgiving than you might think. | As long as your tools are good, selecting the wrong spokes for a wheel is more likely to result from an outright mistake than from a measurement error.

I thank Roger Musson for permission to use the photo below, with cross-sectioned spoke nipples. The spoke threads are the same length in all three examples, but the spoke nipples are of different lengths. A spoke can be threaded in only until the red line in the picture reaches the bottom of the threading in the spoke nipple. Beyond that limit, it will bind. The combination on the left risks breaking the spoke nipple just below the head, because the spoke does not extend up into the head of the nipple. Only the short spoke nipple at the right is really suitable for the spokes shown. | I thank Roger Musson for permission to use the photo below, with cross-sectioned spoke nipples.
