Wheelpro spoke length calculator
This is the calculator I use for all my professional wheelbuilding, over the years I've made enhancements and changes to ensure the calculator is perfect - if it wasn't I would change it! The calculator cannot be used for hubs using straight-pull spokes.
The hub and rim database is not important becuase all wheelbuilders should measure their own components (this is GOOD advice I'm giving you). See the help guide on how to measure components .
