Wolf Tooth Components Cassette Lockring Wrench Insert

This insert is designed to work with Wolf Tooth's Pack Wrench or any standard 1/2-inch drive wrench. It is a modular component, so it requires a separate handle to provide the leverage needed to loosen or tighten your lockring.

It is compatible with most standard centerlock rotor lockrings, but it is specifically designed for those that use the same splined interface as a standard cassette lockring. If your lockring requires an external tool interface, this insert will not fit.

The insert features a built-in magnet that snaps securely into the Pack Wrench or any compatible 1/2-inch drive tool. This keeps the insert from falling out while you are aligning it with the lockring, which is especially helpful when working in tight spaces or on a trailside repair.

While it is engineered for portability and travel, the CNC-machined hardened steel construction is robust enough for regular maintenance. The electroless nickel plating adds a significant layer of corrosion resistance, helping it withstand the wear and tear of frequent use.

This insert is significantly lighter and more compact than a traditional shop-grade cassette tool, weighing only 31 grams. It is the ideal choice if you are building a travel kit or a minimalist tool roll where weight and space are at a premium.
