Special clamping tool for DX fork legs - i.e. the thin outer legs, from 1977 - 1979
Screwed down into the inner leg and held with the special tip on the small tube so that the Allen screw at the bottom can be loosened.
It is usually stuck and can now be loosened easily and quickly. The inner leg can then be removed and the packing boxes and fork legs reinstalled.
It is a known phenomenon, the small tube is difficult to keep inside the fork leg. But here is the solution.
Zinc plated.
