Cassette Wrench

Be the first to review

Style & Size:


More than one way to skin a cat.

Removing a bicycle's cassette requires certain tools and besides needing a lockring tool, you'll either need a chainwhip or a cassette wrench like we have here. We'll make the argument for the Cassette Wrench from Unior here and save your knuckles from slipping whips. It securely grips onto your 11 or 12 tooth cassette sprocket and we feel it provides better ergonomics and comfort, and at 350mm long, more leverage than a chainwhip.

We appreciate that it works with all road and mountain drivetrains including SRAM 1x Eagle and Campy and its crafted from the highest grade tool steel that's hardened and tempered then chrome plated for maximum durability. The handle provides a solid grip and it has a hole through it so you can place the tool on your shop's pegboard and always have it close on hand. This, like all of the Unior tools, is backed by a lifetime warranty.


  • A wrench for securing the cassette while removing it
  • Works with any drivetrain that has either an 11 on 12t sprocket
  • Tool grade steel is durable enough for professional use
  • A comfortable handle and ergonomic position makes it easy to use
