The Park Tool CP-1.2 Cassette Pliers is a professional-grade workshop tool designed to securely hold a bicycle cassette in place during lockring removal. Serving as a modern, highly efficient alternative to a traditional chain whip, these pliers allow mechanics to clamp directly onto the cogs with a simple, one-handed grip.

Key Features

• Wide Compatibility:
  Fully compatible with all 7-speed to 13-speed cassettes, including premium drivetrains like Shimano XTR 12-speed and SRAM eTap AXS. It also works seamlessly on single-speed cassettes featuring a 3/32" cog width.
• Self-Adjusting Jaw Range:
  The knurled jaws automatically clamp down onto cogs ranging from 9 to 24 teeth, eliminating the need for manual adjustments when switching between different bike setups.
• One-Handed Operation:
  Equipped with a spring-loaded return mechanism, the pliers stay open naturally and can be locked onto the cog with one hand. This allows your other hand to remain free for operating the lockring tool and wrench.
• Maximum Leverage:
  Measuring 13.7 inches (35 cm) in length and built from forged steel, the handle provides massive leverage to break loose stubborn, over-torqued cassette lockrings.
• Ergonomic Shop Grip:
  Features dual-density rubber handles for a comfortable, non-slip grip. A handle clip lock ensures the pliers stay closed compactly for easy storage.
