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: HM-350 Strummer 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.
The table below is the theoretical spoke size(s) for the hub(s) and rim(s) combinations listed above:
| Front Hub | Left Spoke | Right Spoke | L/R Tension |
| Radial | 268mm | 268mm | 81% |
| 1 Cross | 270mm | 271mm | 81% |
| 2 Cross | 277 mm | 278 mm | 81% |
| 3 Cross (Recommended) | 287 mm | 288mm | 81% |

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provide accurate and up-to-date information, specification errors may occur due to changes in product specifications (out-of-date information) or input errors.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