Product Information

Full details

The Park Tool FR-2 Freewheel Remover is an essential specialty tool designed for bicycle mechanics and enthusiasts working on older Sun Tour two-notch freewheels. Its primary benefit is the thin-wall construction, which eliminates the need to disassemble axle cones or locknuts before removal, saving significant time during maintenance. While highly durable, users should note that this tool is specifically engineered for a narrow range of legacy components and will not fit modern cassette or freewheel standards.

FAQs

Does this tool work on Shimano cassettes?

No, this tool is specifically designed for Sun Tour two-notch freewheels and will not fit Shimano splined cassettes.

Do I need to remove the axle to use this?

No, the thin-wall construction allows the tool to fit over the axle, so you do not need to remove cones or locknuts.

Can I use an impact wrench with this tool?

It is not recommended. Manual force with a long-handled wrench or a bench vise provides better control and reduces the risk of damaging the notches.

What is the size of the hex base?

The base is 1 inch, making it compatible with a standard adjustable wrench or most shop-grade freewheel sockets.

Why is it important to use a skewer?

The skewer prevents the tool from sliding off the freewheel under heavy pressure, which protects both the tool and the freewheel notches from stripping.

Troubleshooting

The tool keeps slipping out of the notches during use.

Ensure you are using a quick-release skewer or axle nut to firmly hold the tool against the freewheel. Increase the pressure applied by the skewer.

The tool will not fit into the freewheel notches.

Clear out any dirt or grit from the freewheel notches using a pick or compressed air. Verify that your freewheel is a Sun Tour two-notch style.

Pros and Cons

Pros

  • Durable heat-treated alloy construction
  • Time-saving thin-wall design avoids disassembly of hub internals
  • Versatile base fits common shop tools
  • Compact and lightweight for easy storage

Cons

  • Compatible only with specific vintage Sun Tour two-notch systems
  • Requires proper stabilization with a skewer to prevent slipping
  • Not intended for modern cassette lockrings

Setup, Compatibility & Care

Setup: Ensure the freewheel notches are clean of debris before inserting the tool. Always verify that the tool is fully seated into the two notches. Using a skewer to keep the tool pressed against the freewheel is the standard operating procedure to prevent tool slippage and component damage.

Compatibility: This tool is compatible exclusively with Sun Tour two-notch freewheels. The notches measure 25mm from outside to outside, and the internal bore is 10mm. It is not compatible with Shimano or other spline-based locking systems.

Care: Wipe the tool clean with a shop rag after each use. Store in a dry environment to prevent surface oxidation, although the heat-treated finish is resistant to environmental corrosion.
