Park Tool CP-1.2 Cassette Pliers

The CP-1.2 uses a plier-style design that grips the cog directly, allowing for one-handed operation. Unlike a chain whip, which requires you to wrap a chain around the cog and manage slack, these pliers provide a secure, immediate hold that is generally faster and less cumbersome to use.

These pliers are highly versatile and compatible with almost all bicycle cassettes ranging from 7-speed to 13-speed. They also work with single-speed cassettes that use a 3/32-inch cog.

No, the CP-1.2 is designed solely to hold the cassette in place so it doesn't rotate while you loosen the lockring. You will still need a separate cassette lockring tool (like a socket or splined tool) to actually unscrew the lockring itself.

Yes, it is built with forged steel and designed for durability, making it a standard choice for both home mechanics and professional shops. The spring-loaded return and ergonomic grips are specifically intended to handle the repeated use required in a busy workshop environment.

The pliers are designed to securely grip cogs ranging from 9 to 24 teeth. This covers the vast majority of standard cassette configurations found on modern road, mountain, and gravel bikes.
