DT Swiss EXP Star Ratchet Disassembly Tool

No, this specific tool is engineered exclusively for the newer Ratchet EXP hub systems. It will not work with the traditional Star Ratchet systems found on older DT Swiss hubs.

Yes, you will typically need a large adjustable wrench or a bench vise to hold the tool securely while you apply the necessary torque to the hub shell. The tool provides the interface, but you must provide the leverage.

The threaded ring in the EXP system has a very specific spline pattern that requires a precise fit to avoid stripping the soft alloy teeth. Using an improper tool often results in permanent damage to the hub shell, which is why this dedicated interface is required.

You only need this tool if you are performing a full service that requires removing the threaded ring, such as replacing the bearings or servicing the ratchet mechanism deep inside the hub. For basic cleaning and greasing of the star ratchets, you do not need to remove this ring.

The tool itself does not include printed instructions, but DT Swiss provides comprehensive technical manuals on their website for every hub model. We recommend following their specific torque and service procedures to ensure you don't damage your wheelset.
