Unior Tools | Cassette Wrench

Modern control, no chain whip needed.

A precision cassette holding tool designed for mechanics who want a cleaner, more efficient way to service modern drivetrains.

The Unior Cassette Wrench replaces the traditional chain whip with a smarter pin-based design, offering a more secure grip on small-cog cassettes while allowing easy access to the lockring. Built from premium materials and finished for durability, it’s made for consistent workshop use—whether you’re working on high-end 12-speed setups or everyday drivetrains.

Key Features

• Chain Whip Replacement Design
Pins engage directly with the cassette sprocket, eliminating the need for a traditional chain whip.

Ridges on the pins provide strong, slip-resistant engagement on small cogs.

• Lockring Access Opening
Central cutout allows simultaneous use of a cassette lockring tool for efficient removal.
