This combination chain whip and freewheel / lockring remover wrench is heat treated to prevent bending and flexing.

The SR-1 is used when removing cassette-type cogs from rear wheels. It firmly holds the cassette cogs so a lockring tool can be used to remove the cassette lockring.

Features:

• Hardened pins to keep the chain in place
•  A comfortable handle
• Hex opening fits Park Tool freewheel removers
• The SR-1 is approximately 14" long (35cm).
