How to Use This Calculator
- Enter the Hub Flange Diameter and Hub Center to Flange distance in millimeters.
- Set the Effective Rim Diameter (ERD) in millimeters from the rim manufacturer.
- Select your Cross Pattern (Radial through 4-cross) and Spoke Hole Count.
- Review the recommended Spoke Length rounded to the nearest 0.5mm.
- Order spokes using the exact length to minimize trim work during lacing.
