In order to disassemble many of DT's ratchet rear hubs you need a special tool to remove the ring nut (sometimes called the lockring or star ratchet) from the hub body.

This version is for non-EXP hubs (EXP is the newest version of DT's ratchet system, launched in 2020).  We have a different tool for the lockring found in the new EXP hubs, here.

Equivalent to DT Swiss part number HXTXXX00N5027S.

This sale inlcudes the tool only, not the nut itself.

Our tools can be selected either by the bearing size or by the bearing's standard reference code.

Standard references take the form of a three or four digit number, such as 688, or 6902 for example. These codes are often moulded onto the bearing's seal. You might see something like 6902-2RS on the seal. The first digits are the standard reference.  The second part (2RS in this case) refers to the seal type and doesn't matter for tool selection.

Alternatively, tools can be selected by their inside (ID) and outside (OD) diameters and width.

Note that each tool is specific to one bearing size and can’t be used on bearings with different dimensions.
