Warning: This guide is created  to help determine the correct spoke size when assembling a Strummer wheelset. This guide can be used as a reference, but it is important to remember that there is a possibility of inaccurate information due to changes in product sizes/specifications, or user error when inputting data.

Caution: This guide is intended to provide general information and should not be used as the sole reference for determining spoke sizes. There may be a reasonable difference/tolerance in spoke sizes of +/- 1 mm depending on the brand and type of nipple used during ERD measurements or wheelset assembly. Differences may also arise from the rounding process of the numbers that appear during calculations. It is recommended to re-measure and re-calculate before assembly (using the brand and type of spokes & nipples that will be used in the wheelset assembly process). It is recommended to consult a professional bicycle mechanic or manufacturer's specifications before assembling a wheelset. Using the wrong spoke size can be dangerous  safety and wheel structure failure. Always take proper precautions and follow the manufacturer's guidelines to ensure the safety of yourself and others when working on  your bike.
