Professional Spoke Length Calculator

This component is available in multiple spoke counts. Please select one to continue.

This tool provides a precise spoke length based on the numbers you enter. The accuracy of the result depends entirely on the accuracy of your inputs.

Please confirm the following:

• Your ERD is correct. Effective Rim Diameter is the most critical measurement. Always measure it yourself if possible.
• Nipple washers are accounted for. If your ERD measurement *already includes* washer thickness, please leave the 'Nipple Washer Thickness' field at 0 to avoid double-counting.
• Your Hub is correct. Confirm you have selected the exact hub model you intend to use and have verified its dimensions against official manufacturer specifications.

By accepting, you acknowledge that you have verified your inputs and that LoamLabs is not liable for costs incurred from incorrect spoke lengths.

This spoke calculator is a professional-grade tool provided for your convenience. LoamLabs has made every reasonable effort to ensure the accuracy of the component data and the underlying calculation formulas.

• Component Variations: For absolute precision, always measure your components yourself.
• ERD is Critical: A 1mm error in ERD results in a 0.5mm error in spoke length.
• Nipple Washers: Be mindful of whether your ERD measurement includes nipple washer thickness.

By using this tool, you agree that it is your responsibility to verify all measurements. LoamLabs is not liable for any costs incurred from incorrect spoke length calculations.
