Product Information
Full details
The Unior Freewheel Remover (11/12 Tooth) is an essential tool designed for professional mechanics and dedicated home bike builders who need a reliable, high-torque solution for cassette removal. Its key benefit lies in its robust, hardened steel construction which provides the durability necessary for frequent, heavy-duty maintenance tasks. While it offers superior leverage, users should be aware that it is specifically engineered for 11 and 12-tooth sprocket interfaces, making it a specialized tool rather than a universal multi-fit solution.

FAQs
Can I use this for 10-tooth sprockets?
No, this tool is specifically precision-engineered for 11 and 12-tooth sprocket interfaces.
Do I need any other tools to remove my cassette?
Yes, you will need a chain whip to hold the cassette cogs stationary while you use the remover to turn the lockring.
Is this tool suitable for E-bikes?
Yes, provided the cassette lockring matches the 11/12-tooth specification required for this tool.
How should I clean the tool after use?
Simply wipe it down with a clean shop rag to remove degreaser and road debris.
Will this work on non-splined freewheels?
No, this tool is designed for splined cassette lockrings and will not engage with traditional non-splined freewheel systems.
Troubleshooting
The tool slips out of the lockring splines while turning
Ensure the tool is fully seated and use a quick-release skewer or thru-axle (if applicable) to hold the tool tightly against the lockring while you turn it.
Difficulty removing a stuck cassette
Apply a penetrating oil to the threads and let it soak for 15-20 minutes. Ensure your chain whip is held securely to maximize leverage.

Setup, Compatibility & Care
Compatibility: This tool is compatible exclusively with 11 and 12-tooth cassette lockring interfaces. Before starting, verify the lockring specification on your hub to ensure a match.
Usage Guidelines: Always ensure the tool is pushed firmly into the splines before applying pressure. If your cassette is extremely tight, ensure your chain whip is properly engaged on the cogs to prevent rotation.
Care Instructions: After use, wipe the tool clean of grease and road grime with a dry rag. Store in a cool, dry place to prevent corrosion. Periodically check the teeth of the remover for signs of wear or metal fatigue; if the edges appear rounded, replace the tool to protect your components.
