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.

Hub(s) Type: Strummer HM-350 6-Pawl QR (9x100/10x135, 32/32H)

Rim(s) Type: Strummer XC-30 Asymmetric TRS 29" (32/32H)

Warning: Since the rim(s) or rims used have asymmetric specifications, it is important to pay attention to the location of the spoke holes when installing/assembling the wheelset. We recommend using the services of a competent wheelbuilder/mechanic who understands this. Mistakes in assembly can make the wheelset unstable and can endanger the safety of the rider.

Warning: This guide is intended to provide general information and is not intended to be the sole reference (source of information) for spoke sizes. While we strive to provide accurate and up-to-date information, specifications errors may occur due to changes in product specifications (outdated information) or input errors. Please contact us immediately if you find any incorrect or inaccurate information, and we will endeavor to update the information as soon as possible. It is highly recommended to consult a professional bicycle mechanic (wheelbuilder) or manufacturer 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/using your bicycle.
