    How to figure out if I can swap hub with same spokes and rim

    So I am completely ignorant on how spokes are figured out. I have a very nice set of handbuilt wheels that I want to use on a new frame.
    I need to go to a boost rear hub.
    My current rear hub is a Sram X9 QR. How can I figure out if there is another hub that will allow me to have just that hub swapped out without incurring the cost of new spokes?
    Or is that a bad idea in and of itself? Is it okay to re-use spokes?

    I've reused spokes but I'd be very surprised if you bought another brand of hub that has the same dimensions as your old one. It's possible but you'd need to work out the spoke lengths in the same way you would for any other wheel build.

    You can keep swapping hubs until you find one close.

    Unless it's a radial laced wheel (0 cross) wheel hub flange diameter affects spoke length surprisingly little, they can be several mm's different and still use the same spoke length. Check the numbers with a spoke calculator.

    Of course new is better but I've re-used spokes before with good results.

    J.B. is right, because spokes connect to the hub at a tangent, hub size barely matters. You can't go from high flange to centerlock, but a 5mm difference is no problem.
