Wheel Builder Support

Wheel Builder is a bicycle wheel spoke length calculator for iPhone and iPad.

Common Checks

Before ordering spokes, verify ERD, hub flange diameter, center-to-flange distance, spoke count, and lacing pattern against the manufacturer’s published specifications or your own measurements.

Data and Backups

Saved hubs, rims, and builds are stored locally on your device. Use the import and export actions in the app to move JSON backups between devices.
