Wheelbuilding Guide for Strummer Hubs (Spoke Size)

Tips: If you are using a mobile phone/smartphone, use landscape mode to make it more comfortable to read the table below. The best experience reading the table below is with a computer/laptop/tablet.

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

Warning: This guide is intended to provide general information and should not be used as the sole reference for determining spoke sizes. It is recommended that you consult a professional bike mechanic or manufacturer’s specifications before assembling a wheelset. Using the wrong spoke size can compromise the safety and structural failure of the wheel. Always take proper precautions and follow the manufacturer’s guidelines to ensure the safety of yourself and others when working on your bike.

Lacing recommendations: We recommend 3 crosses for 28H and 32H, 2 crosses for 24H.

Note: If the combination you need is not listed in the table below, contact us to update the list below. We can help you with the combination of hubs and rims with the Strummer brand.
