Park Tool FRW-1 - Freewheel Remover Wrench Tool

I normally use a meter long breaker bar with a one-inch socket with park tools cassette tools; however, you need to be aware of more thinks with that combination. I like this tool because you can lock the cassette tool in place with a hex nut. I believe the older version had a thumb nut to lock the cassette tool which seems more sensible and user-friendly than the hex nut, especially if using the tool regularly with different cassette tools. I like the circular cross-section of the handle which is kinder to the hands.

Expensive for a bar of steel with a hex hole and a grub screw, but does the job perfectly, and will almost certainly outlast me.I guess when you are fitting/removing £200-£300 SRAM Eagle cassettes, the price doesn't look so bad.

As above
