What Are the CP-1.2 Cassette Pliers Used For?

The Park Tool CP-1.2 Cassette Pliers are designed to hold a cassette securely while you thread on or remove the lockring. The toothed jaw design grips cassette sprockets firmly without marring the cogs, giving you a controlled hold that resists rotation when you're applying torque with your lockring tool. Built for use alongside a cassette lockring tool and chain whip, the CP-1.2 simplifies cassette work by eliminating the need for a traditional chain whip on many cassette configurations.

Cassette changes are a routine part of bike maintenance, but doing them cleanly requires the right grip on the cassette body. The CP-1.2 makes the job faster and less frustrating, especially on bikes where chain whip access is limited by the frame or rear derailleur.
