Product Information
Full details
The Topeak Duo Spoke Wrench is an essential tool for cyclists and home mechanics who need to maintain wheel trueness and spoke tension on specific high-performance wheelsets. It is specifically engineered for Mavic M7 and M9 spoke nipples, offering a durable, low-profile steel design that provides precise leverage for adjustments. While it is a highly specialized tool that excels at its specific purpose, it is not compatible with standard square spoke nipples found on most budget-friendly wheels, making it a purchase geared toward those running Mavic systems.

FAQs
Will this work on standard Shimano or DT Swiss spokes?
No, this tool is specifically designed for Mavic M7 and M9 spoke nipples and will not fit standard square spoke nipples.
Is this tool suitable for road and mountain bike wheels?
Yes, provided the wheelset uses the Mavic M7 or M9 nipple standard, it is compatible with both road and mountain bike wheels.
How do I know which side is M7 and which is M9?
The sizes are typically stamped or laser-etched onto the tool body for quick identification.
Can I use this to build an entire wheel?
Yes, it is durable enough for full wheel builds, though its low profile makes it better suited for minor truing adjustments or maintenance.
What should I do if I strip a nipple?
If a nipple is stripped, do not force the wrench further; you may need to use a specialized extraction tool or seek professional assistance at a bike shop.
Troubleshooting
Wrench feels loose on the spoke nipple
Verify you are using the correct end of the wrench (M7 vs M9) and ensure the nipple is not already damaged or rounded.
Nipple will not turn despite effort
Apply a small amount of penetrating oil to the spoke threads and let it sit before attempting to adjust; avoid using excessive force that could snap the spoke.

Setup, Compatibility & Care
The Topeak Duo Spoke Wrench requires no setup; it is ready to use immediately. It is strictly compatible with Mavic M7 and M9 size spoke nipples. To maintain the tool's performance, ensure you keep the wrench head clean of road grit and grime, as debris can cause the tool to fit less securely on the nipple. Store the tool in a dry environment to prevent surface corrosion, and periodically inspect the tool's slots to ensure they have not been deformed by excessive force during improper use.
