Felge und Nabe messen, um Speichenlängen zu berechnen: Unterschied zwischen den Versionen

The drawing below is of the same hub shown in the previous two photos (a SRAM DualDrive hub, a 3-speed with a cassette body for hybrid gearing). The dimension in red is the OLD (overlocknut distance), and the dimensions in blue and green are the flange spacings. They are very near the generic ones already given.

With unusual hubs, and especially with a large hub in a small rim, you must measure the flange spacing, or read dimensions from hub specifications. If both flanges are the same distance from the centerline, measure the spacing between the flanges and divide by two. If the two flanges are different distances from the centerline, measure them independently. Resting the locknut against the edge of a workbench or table makes measurement easier. An example is shown below, using the same hub.
