With a used spoke in hand, I want to know to what points I should measure to determine length in the proper way. It seems clear that on the threaded end, the measuring point is the very end of the spoke.

But on the hub end, do I measure from the center of the spoke's head, or from the spot on the spoke that bears against the inside of the hole in the hub flange? I realize this is a VERY small and mostly inconsequential difference, but I'm just the curious sort.

DarronUse a spoke ruler. It has a hole to hook the spoke on and measure it.

ANYWAY: From the threaded tip, to where the spoke would "hang" on the hub flange. Just like you thought.

You can do it just fine with any ruler or tape measure

Great, thanks!

I needed to measure the spokes I removed from an old 27" wheel with steel Araya rim. I'm trying to determine with spocalc if the new 619mm ERD aluminum rim I'm looking at will work with the old spokes and hub (at various X cross lacings).
